  /**
   * The IBM Watson&trade; Speech to Text service provides APIs that use IBM's speech-recognition capabilities to produce
   * transcripts of spoken audio. The service can transcribe speech from various languages and audio formats. In addition
   * to basic transcription, the service can produce detailed information about many different aspects of the audio. For
   * most languages, the service supports two sampling rates, broadband and narrowband. It returns all JSON response
   * content in the UTF-8 character set.
   *
   * For speech recognition, the service supports synchronous and asynchronous HTTP Representational State Transfer (REST)
   * interfaces. It also supports a WebSocket interface that provides a full-duplex, low-latency communication channel:
   * Clients send requests and audio to the service and receive results over a single connection asynchronously.
   *
   * The service also offers two customization interfaces. Use language model customization to expand the vocabulary of a
   * base model with domain-specific terminology. Use acoustic model customization to adapt a base model for the acoustic
   * characteristics of your audio. For language model customization, the service also supports grammars. A grammar is a
   * formal language specification that lets you restrict the phrases that the service can recognize.
   *
   * Language model customization and acoustic model customization are generally available for production use with all
   * language models that are generally available. Grammars are beta functionality for all language models that support
   * language model customization.

       * Recognize audio.
       *
       * Sends audio and returns transcription results for a recognition request. You can pass a maximum of 100 MB and a
       * minimum of 100 bytes of audio with a request. The service automatically detects the endianness of the incoming
       * audio and, for audio that includes multiple channels, downmixes the audio to one-channel mono during transcoding.
       * The method returns only final results; to enable interim results, use the WebSocket API. (With the `curl` command,
       * use the `--data-binary` option to upload the file for the request.)
       *
       * **See also:** [Making a basic HTTP

       *
       * ### Streaming mode
       *
       *  For requests to transcribe live audio as it becomes available, you must set the `Transfer-Encoding` header to
       * `chunked` to use streaming mode. In streaming mode, the service closes the connection (status code 408) if it does
       * not receive at least 15 seconds of audio (including silence) in any 30-second period. The service also closes the
       * connection (status code 400) if it detects no speech for `inactivity_timeout` seconds of streaming audio; use the
       * `inactivity_timeout` parameter to change the default of 30 seconds.
       *
       * **See also:**
       * * [Audio transmission](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#transmission)
       * * [Timeouts](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#timeouts)
       *
       * ### Audio formats (content types)
       *
       *  The service accepts audio in the following formats (MIME types).
       * * For formats that are labeled **Required**, you must use the `Content-Type` header with the request to specify the
       * format of the audio.
       * * For all other formats, you can omit the `Content-Type` header or specify `application/octet-stream` with the
       * header to have the service automatically detect the format of the audio. (With the `curl` command, you can specify
       * either `"Content-Type:"` or `"Content-Type: application/octet-stream"`.)
       *
       * Where indicated, the format that you specify must include the sampling rate and can optionally include the number
       * of channels and the endianness of the audio.
       * * `audio/alaw` (**Required.** Specify the sampling rate (`rate`) of the audio.)
       * * `audio/basic` (**Required.** Use only with narrowband models.)
       * * `audio/flac`
       * * `audio/g729` (Use only with narrowband models.)
       * * `audio/l16` (**Required.** Specify the sampling rate (`rate`) and optionally the number of channels (`channels`)
       * and endianness (`endianness`) of the audio.)
       * * `audio/mp3`
       * * `audio/mpeg`
       * * `audio/mulaw` (**Required.** Specify the sampling rate (`rate`) of the audio.)
       * * `audio/ogg` (The service automatically detects the codec of the input audio.)
       * * `audio/ogg;codecs=opus`
       * * `audio/ogg;codecs=vorbis`
       * * `audio/wav` (Provide audio with a maximum of nine channels.)
       * * `audio/webm` (The service automatically detects the codec of the input audio.)
       * * `audio/webm;codecs=opus`
       * * `audio/webm;codecs=vorbis`
       *
       * The sampling rate of the audio must match the sampling rate of the model for the recognition request: for broadband
       * models, at least 16 kHz; for narrowband models, at least 8 kHz. If the sampling rate of the audio is higher than
       * the minimum required rate, the service down-samples the audio to the appropriate rate. If the sampling rate of the
       * audio is lower than the minimum required rate, the request fails.
       *
       *  **See also:** [Audio
       * formats](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-audio-formats#audio-formats).
       *
       * ### Multipart speech recognition
       *
       *  **Note:** The Watson SDKs do not support multipart speech recognition.
       *
       * The HTTP `POST` method of the service also supports multipart speech recognition. With multipart requests, you pass
       * all audio data as multipart form data. You specify some parameters as request headers and query parameters, but you
       * pass JSON metadata as form data to control most aspects of the transcription. You can use multipart recognition to
       * pass multiple audio files with a single request.
       *
       * Use the multipart approach with browsers for which JavaScript is disabled or when the parameters used with the
       * request are greater than the 8 KB limit imposed by most HTTP servers and proxies. You can encounter this limit, for
       * example, if you want to spot a very large number of keywords.
       *
       * **See also:** [Making a multipart HTTP
       * request](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-http#HTTP-multi).
       *
       * @param {Object} params - The parameters to send to the service.
       * @param {NodeJS.ReadableStream|Buffer} params.audio - The audio to transcribe.
       * @param {string} [params.contentType] - The format (MIME type) of the audio. For more information about specifying
       * an audio format, see **Audio formats (content types)** in the method description.
       * @param {string} [params.model] - The identifier of the model that is to be used for the recognition request. See
       * [Languages and models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-models#models).
       * @param {string} [params.languageCustomizationId] - The customization ID (GUID) of a custom language model that is
       * to be used with the recognition request. The base model of the specified custom language model must match the model
       * specified with the `model` parameter. You must make the request with credentials for the instance of the service
       * that owns the custom model. By default, no custom language model is used. See [Custom
       * models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).
       *
       * **Note:** Use this parameter instead of the deprecated `customization_id` parameter.
       * @param {string} [params.acousticCustomizationId] - The customization ID (GUID) of a custom acoustic model that is
       * to be used with the recognition request. The base model of the specified custom acoustic model must match the model
       * specified with the `model` parameter. You must make the request with credentials for the instance of the service
       * that owns the custom model. By default, no custom acoustic model is used. See [Custom
       * models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).
       * @param {string} [params.baseModelVersion] - The version of the specified base model that is to be used with the
       * recognition request. Multiple versions of a base model can exist when a model is updated for internal improvements.
       * The parameter is intended primarily for use with custom models that have been upgraded for a new base model. The
       * default value depends on whether the parameter is used with or without a custom model. See [Base model
       * version](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#version).
       * @param {number} [params.customizationWeight] - If you specify the customization ID (GUID) of a custom language
       * model with the recognition request, the customization weight tells the service how much weight to give to words
       * from the custom language model compared to those from the base model for the current request.
       *
       * Specify a value between 0.0 and 1.0. Unless a different customization weight was specified for the custom model
       * when it was trained, the default value is 0.3. A customization weight that you specify overrides a weight that was
       * specified when the custom model was trained.
       *
       * The default value yields the best performance in general. Assign a higher value if your audio makes frequent use of
       * OOV words from the custom model. Use caution when setting the weight: a higher value can improve the accuracy of
       * phrases from the custom model's domain, but it can negatively affect performance on non-domain phrases.
       *
       * See [Custom models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).
       * @param {number} [params.inactivityTimeout] - The time in seconds after which, if only silence (no speech) is
       * detected in streaming audio, the connection is closed with a 400 error. The parameter is useful for stopping audio
       * submission from a live microphone when a user simply walks away. Use `-1` for infinity. See [Inactivity
       * timeout](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#timeouts-inactivity).
       * @param {string[]} [params.keywords] - An array of keyword strings to spot in the audio. Each keyword string can
       * include one or more string tokens. Keywords are spotted only in the final results, not in interim hypotheses. If
       * you specify any keywords, you must also specify a keywords threshold. Omit the parameter or specify an empty array
       * if you do not need to spot keywords.
       *
       * You can spot a maximum of 1000 keywords with a single request. A single keyword can have a maximum length of 1024
       * characters, though the maximum effective length for double-byte languages might be shorter. Keywords are
       * case-insensitive.
       *
       * See [Keyword spotting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#keyword_spotting).
       * @param {number} [params.keywordsThreshold] - A confidence value that is the lower bound for spotting a keyword. A
       * word is considered to match a keyword if its confidence is greater than or equal to the threshold. Specify a
       * probability between 0.0 and 1.0. If you specify a threshold, you must also specify one or more keywords. The
       * service performs no keyword spotting if you omit either parameter. See [Keyword
       * spotting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#keyword_spotting).
       * @param {number} [params.maxAlternatives] - The maximum number of alternative transcripts that the service is to
       * return. By default, the service returns a single transcript. If you specify a value of `0`, the service uses the
       * default value, `1`. See [Maximum
       * alternatives](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#max_alternatives).
       * @param {number} [params.wordAlternativesThreshold] - A confidence value that is the lower bound for identifying a
       * hypothesis as a possible word alternative (also known as "Confusion Networks"). An alternative word is considered
       * if its confidence is greater than or equal to the threshold. Specify a probability between 0.0 and 1.0. By default,
       * the service computes no alternative words. See [Word
       * alternatives](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_alternatives).
       * @param {boolean} [params.wordConfidence] - If `true`, the service returns a confidence measure in the range of 0.0
       * to 1.0 for each word. By default, the service returns no word confidence scores. See [Word
       * confidence](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_confidence).
       * @param {boolean} [params.timestamps] - If `true`, the service returns time alignment for each word. By default, no
       * timestamps are returned. See [Word
       * timestamps](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_timestamps).
       * @param {boolean} [params.profanityFilter] - If `true`, the service filters profanity from all output except for
       * keyword results by replacing inappropriate words with a series of asterisks. Set the parameter to `false` to return
       * results with no censoring. Applies to US English transcription only. See [Profanity
       * filtering](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#profanity_filter).
       * @param {boolean} [params.smartFormatting] - If `true`, the service converts dates, times, series of digits and
       * numbers, phone numbers, currency values, and internet addresses into more readable, conventional representations in
       * the final transcript of a recognition request. For US English, the service also converts certain keyword strings to
       * punctuation symbols. By default, the service performs no smart formatting.
       *
       * **Note:** Applies to US English, Japanese, and Spanish transcription only.
       *
       * See [Smart formatting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#smart_formatting).
       * @param {boolean} [params.speakerLabels] - If `true`, the response includes labels that identify which words were
       * spoken by which participants in a multi-person exchange. By default, the service returns no speaker labels. Setting
       * `speaker_labels` to `true` forces the `timestamps` parameter to be `true`, regardless of whether you specify
       * `false` for the parameter.
       *
       * **Note:** Applies to US English, Australian English, German, Japanese, Korean, and Spanish (both broadband and
       * narrowband models) and UK English (narrowband model) transcription only.
       *
       * See [Speaker labels](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#speaker_labels).
       * @param {string} [params.customizationId] - **Deprecated.** Use the `language_customization_id` parameter to specify
       * the customization ID (GUID) of a custom language model that is to be used with the recognition request. Do not
       * specify both parameters with a request.
       * @param {string} [params.grammarName] - The name of a grammar that is to be used with the recognition request. If
       * you specify a grammar, you must also use the `language_customization_id` parameter to specify the name of the
       * custom language model for which the grammar is defined. The service recognizes only strings that are recognized by
       * the specified grammar; it does not recognize other custom words from the model's words resource. See
       * [Grammars](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#grammars-input).
       * @param {boolean} [params.redaction] - If `true`, the service redacts, or masks, numeric data from final
       * transcripts. The feature redacts any number that has three or more consecutive digits by replacing each digit with
       * an `X` character. It is intended to redact sensitive numeric data, such as credit card numbers. By default, the
       * service performs no redaction.
       *
       * When you enable redaction, the service automatically enables smart formatting, regardless of whether you explicitly
       * disable that feature. To ensure maximum security, the service also disables keyword spotting (ignores the
       * `keywords` and `keywords_threshold` parameters) and returns only a single final transcript (forces the
       * `max_alternatives` parameter to be `1`).
       *
       * **Note:** Applies to US English, Japanese, and Korean transcription only.
       *
       * See [Numeric redaction](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#redaction).
       * @param {boolean} [params.audioMetrics] - If `true`, requests detailed information about the signal characteristics
       * of the input audio. The service returns audio metrics with the final transcription results. By default, the service

       * @param {number} [params.endOfPhraseSilenceTime] - If `true`, specifies the duration of the pause interval at which
       * the service splits a transcript into multiple final results. If the service detects pauses or extended silence
       * before it reaches the end of the audio stream, its response can include multiple final results. Silence indicates a
       * point at which the speaker pauses between spoken words or phrases.
       *
       * Specify a value for the pause interval in the range of 0.0 to 120.0.
       * * A value greater than 0 specifies the interval that the service is to use for speech recognition.
       * * A value of 0 indicates that the service is to use the default interval. It is equivalent to omitting the
       * parameter.
       *
       * The default pause interval for most languages is 0.8 seconds; the default for Chinese is 0.6 seconds.

       * multiple final results based on semantic features of the input, for example, at the conclusion of meaningful
       * phrases such as sentences. The service bases its understanding of semantic features on the base language model that
       * you use with a request. Custom language models and grammars can also influence how and where the service splits a
       * transcript. By default, the service splits transcripts based solely on the pause interval.

       * is to perform. Use the parameter to suppress word insertions from music, coughing, and other non-speech events. The
       * service biases the audio it passes for speech recognition by evaluating the input audio against prior models of
       * speech and non-speech activity.
       *
       * Specify a value between 0.0 and 1.0:
       * * 0.0 suppresses all audio (no speech is transcribed).
       * * 0.5 (the default) provides a reasonable compromise for the level of sensitivity.
       * * 1.0 suppresses no audio (speech detection sensitivity is disabled).

       * conversations or background noise.
       *
       * Specify a value in the range of 0.0 to 1.0:

       * Registers a callback URL with the service for use with subsequent asynchronous recognition requests. The service
       * attempts to register, or allowlist, the callback URL if it is not already registered by sending a `GET` request to
       * the callback URL. The service passes a random alphanumeric challenge string via the `challenge_string` parameter of
       * the request. The request includes an `Accept` header that specifies `text/plain` as the required response type.
       *
       * To be registered successfully, the callback URL must respond to the `GET` request from the service. The response
       * must send status code 200 and must include the challenge string in its body. Set the `Content-Type` response header
       * to `text/plain`. Upon receiving this response, the service responds to the original registration request with
       * response code 201.
       *
       * The service sends only a single `GET` request to the callback URL. If the service does not receive a reply with a
       * response code of 200 and a body that echoes the challenge string sent by the service within five seconds, it does
       * not allowlist the URL; it instead sends status code 400 in response to the **Register a callback** request. If the
       * requested callback URL is already allowlisted, the service responds to the initial registration request with
       * response code 200.
       *
       * If you specify a user secret with the request, the service uses it as a key to calculate an HMAC-SHA1 signature of
       * the challenge string in its response to the `POST` request. It sends this signature in the `X-Callback-Signature`
       * header of its `GET` request to the URL during registration. It also uses the secret to calculate a signature over
       * the payload of every callback notification that uses the URL. The signature provides authentication and data
       * integrity for HTTP communications.
       *
       * After you successfully register a callback URL, you can use it with an indefinite number of recognition requests.

      /**
       * Create a job.
       *
       * Creates a job for a new asynchronous recognition request. The job is owned by the instance of the service whose
       * credentials are used to create it. How you learn the status and results of a job depends on the parameters you
       * include with the job creation request:
       * * By callback notification: Include the `callback_url` parameter to specify a URL to which the service is to send
       * callback notifications when the status of the job changes. Optionally, you can also include the `events` and
       * `user_token` parameters to subscribe to specific events and to specify a string that is to be included with each
       * notification for the job.
       * * By polling the service: Omit the `callback_url`, `events`, and `user_token` parameters. You must then use the
       * **Check jobs** or **Check a job** methods to check the status of the job, using the latter to retrieve the results
       * when the job is complete.
       *
       * The two approaches are not mutually exclusive. You can poll the service for job status or obtain results from the
       * service manually even if you include a callback URL. In both cases, you can include the `results_ttl` parameter to
       * specify how long the results are to remain available after the job is complete. Using the HTTPS **Check a job**
       * method to retrieve results is more secure than receiving them via callback notification over HTTP because it
       * provides confidentiality in addition to authentication and data integrity.
       *
       * The method supports the same basic parameters as other HTTP and WebSocket recognition requests. It also supports
       * the following parameters specific to the asynchronous interface:
       * * `callback_url`
       * * `events`
       * * `user_token`
       * * `results_ttl`
       *
       * You can pass a maximum of 1 GB and a minimum of 100 bytes of audio with a request. The service automatically
       * detects the endianness of the incoming audio and, for audio that includes multiple channels, downmixes the audio to
       * one-channel mono during transcoding. The method returns only final results; to enable interim results, use the
       * WebSocket API. (With the `curl` command, use the `--data-binary` option to upload the file for the request.)
       *
       * **See also:** [Creating a job](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-async#create).
       *
       * ### Streaming mode
       *
       *  For requests to transcribe live audio as it becomes available, you must set the `Transfer-Encoding` header to
       * `chunked` to use streaming mode. In streaming mode, the service closes the connection (status code 408) if it does
       * not receive at least 15 seconds of audio (including silence) in any 30-second period. The service also closes the
       * connection (status code 400) if it detects no speech for `inactivity_timeout` seconds of streaming audio; use the
       * `inactivity_timeout` parameter to change the default of 30 seconds.
       *
       * **See also:**
       * * [Audio transmission](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#transmission)
       * * [Timeouts](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#timeouts)
       *
       * ### Audio formats (content types)
       *
       *  The service accepts audio in the following formats (MIME types).
       * * For formats that are labeled **Required**, you must use the `Content-Type` header with the request to specify the
       * format of the audio.
       * * For all other formats, you can omit the `Content-Type` header or specify `application/octet-stream` with the
       * header to have the service automatically detect the format of the audio. (With the `curl` command, you can specify
       * either `"Content-Type:"` or `"Content-Type: application/octet-stream"`.)
       *
       * Where indicated, the format that you specify must include the sampling rate and can optionally include the number
       * of channels and the endianness of the audio.
       * * `audio/alaw` (**Required.** Specify the sampling rate (`rate`) of the audio.)
       * * `audio/basic` (**Required.** Use only with narrowband models.)
       * * `audio/flac`
       * * `audio/g729` (Use only with narrowband models.)
       * * `audio/l16` (**Required.** Specify the sampling rate (`rate`) and optionally the number of channels (`channels`)
       * and endianness (`endianness`) of the audio.)
       * * `audio/mp3`
       * * `audio/mpeg`
       * * `audio/mulaw` (**Required.** Specify the sampling rate (`rate`) of the audio.)
       * * `audio/ogg` (The service automatically detects the codec of the input audio.)
       * * `audio/ogg;codecs=opus`
       * * `audio/ogg;codecs=vorbis`
       * * `audio/wav` (Provide audio with a maximum of nine channels.)
       * * `audio/webm` (The service automatically detects the codec of the input audio.)
       * * `audio/webm;codecs=opus`
       * * `audio/webm;codecs=vorbis`
       *
       * The sampling rate of the audio must match the sampling rate of the model for the recognition request: for broadband
       * models, at least 16 kHz; for narrowband models, at least 8 kHz. If the sampling rate of the audio is higher than
       * the minimum required rate, the service down-samples the audio to the appropriate rate. If the sampling rate of the
       * audio is lower than the minimum required rate, the request fails.
       *
       *  **See also:** [Audio
       * formats](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-audio-formats#audio-formats).
       *
       * @param {Object} params - The parameters to send to the service.
       * @param {NodeJS.ReadableStream|Buffer} params.audio - The audio to transcribe.
       * @param {string} [params.contentType] - The format (MIME type) of the audio. For more information about specifying
       * an audio format, see **Audio formats (content types)** in the method description.
       * @param {string} [params.model] - The identifier of the model that is to be used for the recognition request. See
       * [Languages and models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-models#models).
       * @param {string} [params.callbackUrl] - A URL to which callback notifications are to be sent. The URL must already
       * be successfully allowlisted by using the **Register a callback** method. You can include the same callback URL with
       * any number of job creation requests. Omit the parameter to poll the service for job completion and results.
       *
       * Use the `user_token` parameter to specify a unique user-specified string with each job to differentiate the
       * callback notifications for the jobs.
       * @param {string} [params.events] - If the job includes a callback URL, a comma-separated list of notification events
       * to which to subscribe. Valid events are
       * * `recognitions.started` generates a callback notification when the service begins to process the job.
       * * `recognitions.completed` generates a callback notification when the job is complete. You must use the **Check a
       * job** method to retrieve the results before they time out or are deleted.
       * * `recognitions.completed_with_results` generates a callback notification when the job is complete. The
       * notification includes the results of the request.
       * * `recognitions.failed` generates a callback notification if the service experiences an error while processing the
       * job.
       *
       * The `recognitions.completed` and `recognitions.completed_with_results` events are incompatible. You can specify
       * only of the two events.
       *
       * If the job includes a callback URL, omit the parameter to subscribe to the default events: `recognitions.started`,
       * `recognitions.completed`, and `recognitions.failed`. If the job does not include a callback URL, omit the
       * parameter.
       * @param {string} [params.userToken] - If the job includes a callback URL, a user-specified string that the service
       * is to include with each callback notification for the job; the token allows the user to maintain an internal
       * mapping between jobs and notification events. If the job does not include a callback URL, omit the parameter.
       * @param {number} [params.resultsTtl] - The number of minutes for which the results are to be available after the job
       * has finished. If not delivered via a callback, the results must be retrieved within this time. Omit the parameter
       * to use a time to live of one week. The parameter is valid with or without a callback URL.
       * @param {string} [params.languageCustomizationId] - The customization ID (GUID) of a custom language model that is
       * to be used with the recognition request. The base model of the specified custom language model must match the model
       * specified with the `model` parameter. You must make the request with credentials for the instance of the service
       * that owns the custom model. By default, no custom language model is used. See [Custom
       * models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).
       *
       * **Note:** Use this parameter instead of the deprecated `customization_id` parameter.
       * @param {string} [params.acousticCustomizationId] - The customization ID (GUID) of a custom acoustic model that is
       * to be used with the recognition request. The base model of the specified custom acoustic model must match the model
       * specified with the `model` parameter. You must make the request with credentials for the instance of the service
       * that owns the custom model. By default, no custom acoustic model is used. See [Custom
       * models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).
       * @param {string} [params.baseModelVersion] - The version of the specified base model that is to be used with the
       * recognition request. Multiple versions of a base model can exist when a model is updated for internal improvements.
       * The parameter is intended primarily for use with custom models that have been upgraded for a new base model. The
       * default value depends on whether the parameter is used with or without a custom model. See [Base model
       * version](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#version).
       * @param {number} [params.customizationWeight] - If you specify the customization ID (GUID) of a custom language
       * model with the recognition request, the customization weight tells the service how much weight to give to words
       * from the custom language model compared to those from the base model for the current request.
       *
       * Specify a value between 0.0 and 1.0. Unless a different customization weight was specified for the custom model
       * when it was trained, the default value is 0.3. A customization weight that you specify overrides a weight that was
       * specified when the custom model was trained.
       *
       * The default value yields the best performance in general. Assign a higher value if your audio makes frequent use of
       * OOV words from the custom model. Use caution when setting the weight: a higher value can improve the accuracy of
       * phrases from the custom model's domain, but it can negatively affect performance on non-domain phrases.
       *
       * See [Custom models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).
       * @param {number} [params.inactivityTimeout] - The time in seconds after which, if only silence (no speech) is
       * detected in streaming audio, the connection is closed with a 400 error. The parameter is useful for stopping audio
       * submission from a live microphone when a user simply walks away. Use `-1` for infinity. See [Inactivity
       * timeout](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#timeouts-inactivity).
       * @param {string[]} [params.keywords] - An array of keyword strings to spot in the audio. Each keyword string can
       * include one or more string tokens. Keywords are spotted only in the final results, not in interim hypotheses. If
       * you specify any keywords, you must also specify a keywords threshold. Omit the parameter or specify an empty array
       * if you do not need to spot keywords.
       *
       * You can spot a maximum of 1000 keywords with a single request. A single keyword can have a maximum length of 1024
       * characters, though the maximum effective length for double-byte languages might be shorter. Keywords are
       * case-insensitive.
       *
       * See [Keyword spotting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#keyword_spotting).
       * @param {number} [params.keywordsThreshold] - A confidence value that is the lower bound for spotting a keyword. A
       * word is considered to match a keyword if its confidence is greater than or equal to the threshold. Specify a
       * probability between 0.0 and 1.0. If you specify a threshold, you must also specify one or more keywords. The
       * service performs no keyword spotting if you omit either parameter. See [Keyword
       * spotting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#keyword_spotting).
       * @param {number} [params.maxAlternatives] - The maximum number of alternative transcripts that the service is to
       * return. By default, the service returns a single transcript. If you specify a value of `0`, the service uses the
       * default value, `1`. See [Maximum
       * alternatives](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#max_alternatives).
       * @param {number} [params.wordAlternativesThreshold] - A confidence value that is the lower bound for identifying a
       * hypothesis as a possible word alternative (also known as "Confusion Networks"). An alternative word is considered
       * if its confidence is greater than or equal to the threshold. Specify a probability between 0.0 and 1.0. By default,
       * the service computes no alternative words. See [Word
       * alternatives](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_alternatives).
       * @param {boolean} [params.wordConfidence] - If `true`, the service returns a confidence measure in the range of 0.0
       * to 1.0 for each word. By default, the service returns no word confidence scores. See [Word
       * confidence](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_confidence).
       * @param {boolean} [params.timestamps] - If `true`, the service returns time alignment for each word. By default, no
       * timestamps are returned. See [Word
       * timestamps](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_timestamps).
       * @param {boolean} [params.profanityFilter] - If `true`, the service filters profanity from all output except for
       * keyword results by replacing inappropriate words with a series of asterisks. Set the parameter to `false` to return
       * results with no censoring. Applies to US English transcription only. See [Profanity
       * filtering](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#profanity_filter).
       * @param {boolean} [params.smartFormatting] - If `true`, the service converts dates, times, series of digits and
       * numbers, phone numbers, currency values, and internet addresses into more readable, conventional representations in
       * the final transcript of a recognition request. For US English, the service also converts certain keyword strings to
       * punctuation symbols. By default, the service performs no smart formatting.
       *
       * **Note:** Applies to US English, Japanese, and Spanish transcription only.
       *
       * See [Smart formatting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#smart_formatting).
       * @param {boolean} [params.speakerLabels] - If `true`, the response includes labels that identify which words were
       * spoken by which participants in a multi-person exchange. By default, the service returns no speaker labels. Setting
       * `speaker_labels` to `true` forces the `timestamps` parameter to be `true`, regardless of whether you specify
       * `false` for the parameter.
       *
       * **Note:** Applies to US English, Australian English, German, Japanese, Korean, and Spanish (both broadband and
       * narrowband models) and UK English (narrowband model) transcription only.
       *
       * See [Speaker labels](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#speaker_labels).
       * @param {string} [params.customizationId] - **Deprecated.** Use the `language_customization_id` parameter to specify
       * the customization ID (GUID) of a custom language model that is to be used with the recognition request. Do not
       * specify both parameters with a request.
       * @param {string} [params.grammarName] - The name of a grammar that is to be used with the recognition request. If
       * you specify a grammar, you must also use the `language_customization_id` parameter to specify the name of the
       * custom language model for which the grammar is defined. The service recognizes only strings that are recognized by
       * the specified grammar; it does not recognize other custom words from the model's words resource. See
       * [Grammars](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#grammars-input).
       * @param {boolean} [params.redaction] - If `true`, the service redacts, or masks, numeric data from final
       * transcripts. The feature redacts any number that has three or more consecutive digits by replacing each digit with
       * an `X` character. It is intended to redact sensitive numeric data, such as credit card numbers. By default, the
       * service performs no redaction.
       *
       * When you enable redaction, the service automatically enables smart formatting, regardless of whether you explicitly
       * disable that feature. To ensure maximum security, the service also disables keyword spotting (ignores the
       * `keywords` and `keywords_threshold` parameters) and returns only a single final transcript (forces the
       * `max_alternatives` parameter to be `1`).
       *
       * **Note:** Applies to US English, Japanese, and Korean transcription only.
       *
       * See [Numeric redaction](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#redaction).
       * @param {boolean} [params.processingMetrics] - If `true`, requests processing metrics about the service's
       * transcription of the input audio. The service returns processing metrics at the interval specified by the
       * `processing_metrics_interval` parameter. It also returns processing metrics for transcription events, for example,
       * for final and interim results. By default, the service returns no processing metrics.
       *
       * See [Processing
       * metrics](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-metrics#processing_metrics).
       * @param {number} [params.processingMetricsInterval] - Specifies the interval in real wall-clock seconds at which the
       * service is to return processing metrics. The parameter is ignored unless the `processing_metrics` parameter is set
       * to `true`.
       *
       * The parameter accepts a minimum value of 0.1 seconds. The level of precision is not restricted, so you can specify
       * values such as 0.25 and 0.125.
       *
       * The service does not impose a maximum value. If you want to receive processing metrics only for transcription
       * events instead of at periodic intervals, set the value to a large number. If the value is larger than the duration
       * of the audio, the service returns processing metrics only for transcription events.
       *
       * See [Processing
       * metrics](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-metrics#processing_metrics).
       * @param {boolean} [params.audioMetrics] - If `true`, requests detailed information about the signal characteristics
       * of the input audio. The service returns audio metrics with the final transcription results. By default, the service
       * returns no audio metrics.
       *
       * See [Audio metrics](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-metrics#audio_metrics).
       * @param {number} [params.endOfPhraseSilenceTime] - If `true`, specifies the duration of the pause interval at which
       * the service splits a transcript into multiple final results. If the service detects pauses or extended silence
       * before it reaches the end of the audio stream, its response can include multiple final results. Silence indicates a
       * point at which the speaker pauses between spoken words or phrases.
       *
       * Specify a value for the pause interval in the range of 0.0 to 120.0.
       * * A value greater than 0 specifies the interval that the service is to use for speech recognition.
       * * A value of 0 indicates that the service is to use the default interval. It is equivalent to omitting the
       * parameter.
       *
       * The default pause interval for most languages is 0.8 seconds; the default for Chinese is 0.6 seconds.
       *
       * See [End of phrase silence
       * time](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#silence_time).
       * @param {boolean} [params.splitTranscriptAtPhraseEnd] - If `true`, directs the service to split the transcript into
       * multiple final results based on semantic features of the input, for example, at the conclusion of meaningful
       * phrases such as sentences. The service bases its understanding of semantic features on the base language model that
       * you use with a request. Custom language models and grammars can also influence how and where the service splits a
       * transcript. By default, the service splits transcripts based solely on the pause interval.
       *
       * See [Split transcript at phrase
       * end](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#split_transcript).
       * @param {number} [params.speechDetectorSensitivity] - The sensitivity of speech activity detection that the service
       * is to perform. Use the parameter to suppress word insertions from music, coughing, and other non-speech events. The
       * service biases the audio it passes for speech recognition by evaluating the input audio against prior models of
       * speech and non-speech activity.
       *
       * Specify a value between 0.0 and 1.0:
       * * 0.0 suppresses all audio (no speech is transcribed).
       * * 0.5 (the default) provides a reasonable compromise for the level of sensitivity.
       * * 1.0 suppresses no audio (speech detection sensitivity is disabled).
       *
       * The values increase on a monotonic curve. See [Speech Activity
       * Detection](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#detection).
       * @param {number} [params.backgroundAudioSuppression] - The level to which the service is to suppress background
       * audio based on its volume to prevent it from being transcribed as speech. Use the parameter to suppress side
       * conversations or background noise.
       *
       * Specify a value in the range of 0.0 to 1.0:
       * * 0.0 (the default) provides no suppression (background audio suppression is disabled).
       * * 0.5 provides a reasonable level of audio suppression for general usage.
       * * 1.0 suppresses all audio (no audio is transcribed).
       *
       * The values increase on a monotonic curve. See [Speech Activity
       * Detection](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#detection).

       * Create a custom language model.
       *
       * Creates a new custom language model for a specified base model. The custom language model can be used only with the
       * base model for which it is created. The model is owned by the instance of the service whose credentials are used to
       * create it.
       *
       * You can create a maximum of 1024 custom language models per owning credentials. The service returns an error if you
       * attempt to create more than 1024 models. You do not lose any models, but you cannot create any more until your
       * model count is below the limit.
       *
       * **See also:** [Create a custom language
       * model](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-languageCreate#createModel-language).
       *
       * @param {Object} params - The parameters to send to the service.
       * @param {string} params.name - A user-defined name for the new custom language model. Use a name that is unique
       * among all custom language models that you own. Use a localized name that matches the language of the custom model.
       * Use a name that describes the domain of the custom model, such as `Medical custom model` or `Legal custom model`.
       * @param {string} params.baseModelName - The name of the base language model that is to be customized by the new
       * custom language model. The new custom model can be used only with the base model that it customizes.
       *
       * To determine whether a base model supports language model customization, use the **Get a model** method and check
       * that the attribute `custom_language_model` is set to `true`. You can also refer to [Language support for
       * customization](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-customization#languageSupport).
       * @param {string} [params.dialect] - The dialect of the specified language that is to be used with the custom
       * language model. For most languages, the dialect matches the language of the base model by default. For example,
       * `en-US` is used for either of the US English language models.
       *
       * For a Spanish language, the service creates a custom language model that is suited for speech in one of the
       * following dialects:
       * * `es-ES` for Castilian Spanish (`es-ES` models)
       * * `es-LA` for Latin American Spanish (`es-AR`, `es-CL`, `es-CO`, and `es-PE` models)
       * * `es-US` for Mexican (North American) Spanish (`es-MX` models)
       *
       * The parameter is meaningful only for Spanish models, for which you can always safely omit the parameter to have the
       * service create the correct mapping.
       *
       * If you specify the `dialect` parameter for non-Spanish language models, its value must match the language of the
       * base model. If you specify the `dialect` for Spanish language models, its value must match one of the defined
       * mappings as indicated (`es-ES`, `es-LA`, or `es-MX`). All dialect values are case-insensitive.
       * @param {string} [params.description] - A description of the new custom language model. Use a localized description
       * that matches the language of the custom model.
       * @param {OutgoingHttpHeaders} [params.headers] - Custom request headers
       * @returns {Promise<SpeechToTextV1.Response<SpeechToTextV1.LanguageModel>>}

       * @param {string} params.customizationId - The customization ID (GUID) of the custom language model that is to be
       * used for the request. You must make the request with credentials for the instance of the service that owns the
       * custom model.
       * @param {string} [params.wordTypeToAdd] - The type of words from the custom language model's words resource on which
       * to train the model:
       * * `all` (the default) trains the model on all new words, regardless of whether they were extracted from corpora or
       * grammars or were added or modified by the user.
       * * `user` trains the model only on new words that were added or modified by the user directly. The model is not
       * trained on new words extracted from corpora or grammars.
       * @param {number} [params.customizationWeight] - Specifies a customization weight for the custom language model. The
       * customization weight tells the service how much weight to give to words from the custom language model compared to
       * those from the base model for speech recognition. Specify a value between 0.0 and 1.0; the default is 0.3.
       *
       * The default value yields the best performance in general. Assign a higher value if your audio makes frequent use of
       * OOV words from the custom model. Use caution when setting the weight: a higher value can improve the accuracy of
       * phrases from the custom model's domain, but it can negatively affect performance on non-domain phrases.
       *
       * The value that you assign is used for all recognition requests that use the model. You can override it for any
       * recognition request by specifying a customization weight for that request.

       * Add a corpus.
       *
       * Adds a single corpus text file of new training data to a custom language model. Use multiple requests to submit
       * multiple corpus text files. You must use credentials for the instance of the service that owns a model to add a
       * corpus to it. Adding a corpus does not affect the custom language model until you train the model for the new data
       * by using the **Train a custom language model** method.
       *
       * Submit a plain text file that contains sample sentences from the domain of interest to enable the service to
       * extract words in context. The more sentences you add that represent the context in which speakers use words from
       * the domain, the better the service's recognition accuracy.
       *
       * The call returns an HTTP 201 response code if the corpus is valid. The service then asynchronously processes the
       * contents of the corpus and automatically extracts new words that it finds. This operation can take on the order of
       * minutes to complete depending on the total number of words and the number of new words in the corpus, as well as
       * the current load on the service. You cannot submit requests to add additional resources to the custom model or to
       * train the model until the service's analysis of the corpus for the current request completes. Use the **List a
       * corpus** method to check the status of the analysis.
       *
       * The service auto-populates the model's words resource with words from the corpus that are not found in its base
       * vocabulary. These words are referred to as out-of-vocabulary (OOV) words. After adding a corpus, you must validate
       * the words resource to ensure that each OOV word's definition is complete and valid. You can use the **List custom
       * words** method to examine the words resource. You can use other words method to eliminate typos and modify how
       * words are pronounced as needed.
       *
       * To add a corpus file that has the same name as an existing corpus, set the `allow_overwrite` parameter to `true`;
       * otherwise, the request fails. Overwriting an existing corpus causes the service to process the corpus text file and
       * extract OOV words anew. Before doing so, it removes any OOV words associated with the existing corpus from the
       * model's words resource unless they were also added by another corpus or grammar, or they have been modified in some
       * way with the **Add custom words** or **Add a custom word** method.
       *
       * The service limits the overall amount of data that you can add to a custom model to a maximum of 10 million total
       * words from all sources combined. Also, you can add no more than 90 thousand custom (OOV) words to a model. This
       * includes words that the service extracts from corpora and grammars, and words that you add directly.

       * both of the optional `sounds_like` and `display_as` fields for each word.
       * * The `sounds_like` field provides an array of one or more pronunciations for the word. Use the parameter to
       * specify how the word can be pronounced by users. Use the parameter for words that are difficult to pronounce,
       * foreign words, acronyms, and so on. For example, you might specify that the word `IEEE` can sound like `i triple
       * e`. You can specify a maximum of five sounds-like pronunciations for a word. If you omit the `sounds_like` field,
       * the service attempts to set the field to its pronunciation of the word. It cannot generate a pronunciation for all
       * words, so you must review the word's definition to ensure that it is complete and valid.
       * * The `display_as` field provides a different way of spelling the word in a transcript. Use the parameter when you
       * want the word to appear different from its usual representation or from its spelling in training data. For example,
       * you might indicate that the word `IBM(trademark)` is to be displayed as `IBM&trade;`.
       *
       * If you add a custom word that already exists in the words resource for the custom model, the new definition
       * overwrites the existing data for the word. If the service encounters an error with the input data, it returns a
       * failure code and does not add any of the words to the words resource.
       *
       * The call returns an HTTP 201 response code if the input data is valid. It then asynchronously processes the words
       * to add them to the model's words resource. The time that it takes for the analysis to complete depends on the
       * number of new words that you add but is generally faster than adding a corpus or grammar.
       *
       * You can monitor the status of the request by using the **List a custom language model** method to poll the model's
       * status. Use a loop to check the status every 10 seconds. The method returns a `Customization` object that includes
       * a `status` field. A status of `ready` means that the words have been added to the custom model. The service cannot
       * accept requests to add new data or to train the model until the existing request completes.
       *
       * You can use the **List custom words** or **List a custom word** method to review the words that you add. Words with
       * an invalid `sounds_like` field include an `error` field that describes the problem. You can use other words-related
       * methods to correct errors, eliminate typos, and modify how words are pronounced as needed.

       * Add a custom word.

       * Adds a custom word to a custom language model. The service populates the words resource for a custom model with
       * out-of-vocabulary (OOV) words from each corpus or grammar that is added to the model. You can use this method to
       * add a word or to modify an existing word in the words resource. The words resource for a model can contain a
       * maximum of 90 thousand custom (OOV) words. This includes words that the service extracts from corpora and grammars
       * and words that you add directly.
       *
       * You must use credentials for the instance of the service that owns a model to add or modify a custom word for the
       * model. Adding or modifying a custom word does not affect the custom model until you train the model for the new
       * data by using the **Train a custom language model** method.
       *
       * Use the `word_name` parameter to specify the custom word that is to be added or modified. Use the `CustomWord`
       * object to provide one or both of the optional `sounds_like` and `display_as` fields for the word.
       * * The `sounds_like` field provides an array of one or more pronunciations for the word. Use the parameter to
       * specify how the word can be pronounced by users. Use the parameter for words that are difficult to pronounce,
       * foreign words, acronyms, and so on. For example, you might specify that the word `IEEE` can sound like `i triple
       * e`. You can specify a maximum of five sounds-like pronunciations for a word. If you omit the `sounds_like` field,
       * the service attempts to set the field to its pronunciation of the word. It cannot generate a pronunciation for all
       * words, so you must review the word's definition to ensure that it is complete and valid.
       * * The `display_as` field provides a different way of spelling the word in a transcript. Use the parameter when you

       * you might indicate that the word `IBM(trademark)` is to be displayed as `IBM&trade;`.

       * @param {string} params.customizationId - The customization ID (GUID) of the custom language model that is to be
       * used for the request. You must make the request with credentials for the instance of the service that owns the
       * custom model.
       * @param {string} params.grammarName - The name of the new grammar for the custom language model. Use a localized
       * name that matches the language of the custom model and reflects the contents of the grammar.
       * * Include a maximum of 128 characters in the name.
       * * Do not use characters that need to be URL-encoded. For example, do not use spaces, slashes, backslashes, colons,
       * ampersands, double quotes, plus signs, equals signs, questions marks, and so on in the name. (The service does not
       * prevent the use of these characters. But because they must be URL-encoded wherever used, their use is strongly
       * discouraged.)
       * * Do not use the name of an existing grammar or corpus that is already defined for the custom model.
       * * Do not use the name `user`, which is reserved by the service to denote custom words that are added or modified by
       * the user.
       * * Do not use the name `base_lm` or `default_lm`. Both names are reserved for future use by the service.
       * @param {string|NodeJS.ReadableStream|Buffer} params.grammarFile - A plain text file that contains the grammar in
       * the format specified by the `Content-Type` header. Encode the file in UTF-8 (ASCII is a subset of UTF-8). Using any
       * other encoding can lead to issues when compiling the grammar or to unexpected results in decoding. The service
       * ignores an encoding that is specified in the header of the grammar.
       *
       * With the `curl` command, use the `--data-binary` option to upload the file for the request.
       * @param {string} params.contentType - The format (MIME type) of the grammar file:
       * * `application/srgs` for Augmented Backus-Naur Form (ABNF), which uses a plain-text representation that is similar
       * to traditional BNF grammars.
       * * `application/srgs+xml` for XML Form, which uses XML elements to represent the grammar.
       * @param {boolean} [params.allowOverwrite] - If `true`, the specified grammar overwrites an existing grammar with the
       * same name. If `false`, the request fails if a grammar with the same name already exists. The parameter has no

       * length of its cumulative audio data. For example, it takes approximately 2 hours to train a model that contains a
       * total of 2 hours of audio. The method returns an HTTP 200 response code to indicate that the training process has
       * begun.
       *
       * You can monitor the status of the training by using the **Get a custom acoustic model** method to poll the model's
       * status. Use a loop to check the status once a minute. The method returns an `AcousticModel` object that includes
       * `status` and `progress` fields. A status of `available` indicates that the custom model is trained and ready to
       * use. The service cannot train a model while it is handling another request for the model. The service cannot accept
       * subsequent training requests, or requests to add new audio resources, until the existing training request
       * completes.
       *
       * You can use the optional `custom_language_model_id` parameter to specify the GUID of a separately created custom
       * language model that is to be used during training. Train with a custom language model if you have verbatim
       * transcriptions of the audio files that you have added to the custom model or you have either corpora (text files)
       * or a list of words that are relevant to the contents of the audio files. For training to succeed, both of the
       * custom models must be based on the same version of the same base model, and the custom language model must be fully
       * trained and available.

       *
       *  Training can fail to start for the following reasons:
       * * The service is currently handling another request for the custom model, such as another training request or a
       * request to add audio resources to the model.
       * * The custom model contains less than 10 minutes or more than 200 hours of audio data.
       * * You passed a custom language model with the `custom_language_model_id` query parameter that is not in the
       * available state. A custom language model must be fully trained and available to be used to train a custom acoustic
       * model.
       * * You passed an incompatible custom language model with the `custom_language_model_id` query parameter. Both custom
       * models must be based on the same version of the same base model.
       * * The custom model contains one or more invalid audio resources. You can correct the invalid audio resources or set
       * the `strict` parameter to `false` to exclude the invalid resources from the training. The model must contain at
       * least one valid resource for training to succeed.
       *
       * @param {Object} params - The parameters to send to the service.
       * @param {string} params.customizationId - The customization ID (GUID) of the custom acoustic model that is to be

       * custom model.
       * @param {string} [params.customLanguageModelId] - The customization ID (GUID) of a custom language model that is to
       * be used during training of the custom acoustic model. Specify a custom language model that has been trained with
       * verbatim transcriptions of the audio resources or that contains words that are relevant to the contents of the

       * Add an audio resource.
       *
       * Adds an audio resource to a custom acoustic model. Add audio content that reflects the acoustic characteristics of
       * the audio that you plan to transcribe. You must use credentials for the instance of the service that owns a model
       * to add an audio resource to it. Adding audio data does not affect the custom acoustic model until you train the
       * model for the new data by using the **Train a custom acoustic model** method.
       *
       * You can add individual audio files or an archive file that contains multiple audio files. Adding multiple audio
       * files via a single archive file is significantly more efficient than adding each file individually. You can add
       * audio resources in any format that the service supports for speech recognition.
       *
       * You can use this method to add any number of audio resources to a custom model by calling the method once for each
       * audio or archive file. You can add multiple different audio resources at the same time. You must add a minimum of
       * 10 minutes and a maximum of 200 hours of audio that includes speech, not just silence, to a custom acoustic model
       * before you can train it. No audio resource, audio- or archive-type, can be larger than 100 MB. To add an audio
       * resource that has the same name as an existing audio resource, set the `allow_overwrite` parameter to `true`;
       * otherwise, the request fails.
       *
       * The method is asynchronous. It can take several seconds or minutes to complete depending on the duration of the
       * audio and, in the case of an archive file, the total number of audio files being processed. The service returns a
       * 201 response code if the audio is valid. It then asynchronously analyzes the contents of the audio file or files
       * and automatically extracts information about the audio such as its length, sampling rate, and encoding. You cannot
       * submit requests to train or upgrade the model until the service's analysis of all audio resources for current
       * requests completes.
       *
       * To determine the status of the service's analysis of the audio, use the **Get an audio resource** method to poll
       * the status of the audio. The method accepts the customization ID of the custom model and the name of the audio
       * resource, and it returns the status of the resource. Use a loop to check the status of the audio every few seconds
       * until it becomes `ok`.
       *
       * **See also:** [Add audio to the custom acoustic
       * model](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-acoustic#addAudio).
       *
       * ### Content types for audio-type resources
       *
       *  You can add an individual audio file in any format that the service supports for speech recognition. For an
       * audio-type resource, use the `Content-Type` parameter to specify the audio format (MIME type) of the audio file,
       * including specifying the sampling rate, channels, and endianness where indicated.
       * * `audio/alaw` (Specify the sampling rate (`rate`) of the audio.)
       * * `audio/basic` (Use only with narrowband models.)
       * * `audio/flac`
       * * `audio/g729` (Use only with narrowband models.)
       * * `audio/l16` (Specify the sampling rate (`rate`) and optionally the number of channels (`channels`) and endianness
       * (`endianness`) of the audio.)
       * * `audio/mp3`
       * * `audio/mpeg`
       * * `audio/mulaw` (Specify the sampling rate (`rate`) of the audio.)
       * * `audio/ogg` (The service automatically detects the codec of the input audio.)
       * * `audio/ogg;codecs=opus`
       * * `audio/ogg;codecs=vorbis`
       * * `audio/wav` (Provide audio with a maximum of nine channels.)
       * * `audio/webm` (The service automatically detects the codec of the input audio.)
       * * `audio/webm;codecs=opus`
       * * `audio/webm;codecs=vorbis`
       *
       * The sampling rate of an audio file must match the sampling rate of the base model for the custom model: for
       * broadband models, at least 16 kHz; for narrowband models, at least 8 kHz. If the sampling rate of the audio is
       * higher than the minimum required rate, the service down-samples the audio to the appropriate rate. If the sampling
       * rate of the audio is lower than the minimum required rate, the service labels the audio file as `invalid`.
       *
       *  **See also:** [Audio
       * formats](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-audio-formats#audio-formats).
       *
       * ### Content types for archive-type resources
       *
       *  You can add an archive file (**.zip** or **.tar.gz** file) that contains audio files in any format that the
       * service supports for speech recognition. For an archive-type resource, use the `Content-Type` parameter to specify
       * the media type of the archive file:
       * * `application/zip` for a **.zip** file
       * * `application/gzip` for a **.tar.gz** file.
       *
       * When you add an archive-type resource, the `Contained-Content-Type` header is optional depending on the format of
       * the files that you are adding:
       * * For audio files of type `audio/alaw`, `audio/basic`, `audio/l16`, or `audio/mulaw`, you must use the
       * `Contained-Content-Type` header to specify the format of the contained audio files. Include the `rate`, `channels`,
       * and `endianness` parameters where necessary. In this case, all audio files contained in the archive file must have
       * the same audio format.
       * * For audio files of all other types, you can omit the `Contained-Content-Type` header. In this case, the audio
       * files contained in the archive file can have any of the formats not listed in the previous bullet. The audio files
       * do not need to have the same format.
       *
       * Do not use the `Contained-Content-Type` header when adding an audio-type resource.
       *
       * ### Naming restrictions for embedded audio files
       *
       *  The name of an audio file that is contained in an archive-type resource can include a maximum of 128 characters.
       * This includes the file extension and all elements of the name (for example, slashes).
       *
       * @param {Object} params - The parameters to send to the service.
       * @param {string} params.customizationId - The customization ID (GUID) of the custom acoustic model that is to be
       * used for the request. You must make the request with credentials for the instance of the service that owns the
       * custom model.
       * @param {string} params.audioName - The name of the new audio resource for the custom acoustic model. Use a
       * localized name that matches the language of the custom model and reflects the contents of the resource.
       * * Include a maximum of 128 characters in the name.
       * * Do not use characters that need to be URL-encoded. For example, do not use spaces, slashes, backslashes, colons,
       * ampersands, double quotes, plus signs, equals signs, questions marks, and so on in the name. (The service does not
       * prevent the use of these characters. But because they must be URL-encoded wherever used, their use is strongly
       * discouraged.)
       * * Do not use the name of an audio resource that has already been added to the custom model.
       * @param {NodeJS.ReadableStream|Buffer} params.audioResource - The audio resource that is to be added to the custom
