        diarization_config instead. This field will be DEPRECATED soon.
      enableAutomaticPunctuation: *Optional* If 'true', adds punctuation to
        recognition result hypotheses. This feature is only available in select
        languages. Setting this for requests in other languages has no effect at
        all. The default 'false' value does not add punctuation to result
        hypotheses. Note: This is currently offered as an experimental service,
        complimentary to all users. In the future this may be exclusively
        available as a premium feature.
      enableSeparateRecognitionPerChannel: This needs to be set to `true`
        explicitly and `audio_channel_count` > 1 to get each channel recognized
        separately. The recognition result will contain a `channel_tag` field to
        state which channel that result belongs to. If this is not true, we will
        only recognize the first channel. The request is billed cumulatively for
        all channels recognized: `audio_channel_count` multiplied by the length
        of the audio.
      enableSpeakerDiarization: *Optional* If 'true', enables speaker detection
        for each recognized word in the top alternative of the recognition
        result using a speaker_tag provided in the WordInfo. Note: Use
        diarization_config instead. This field will be DEPRECATED soon.
      enableWordConfidence: *Optional* If `true`, the top result includes a list
        of words and the confidence for those words. If `false`, no word-level
        confidence information is returned. The default is `false`.
      enableWordTimeOffsets: *Optional* If `true`, the top result includes a
        list of words and the start and end time offsets (timestamps) for those
        words. If `false`, no word-level time offset information is returned.
        The default is `false`.
      encoding: Encoding of audio data sent in all `RecognitionAudio` messages.
        This field is optional for `FLAC` and `WAV` audio files and required for
        all other audio formats. For details, see AudioEncoding.
      languageCode: *Required* The language of the supplied audio as a
        [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag.
        Example: "en-US". See [Language Support](/speech-to-text/docs/languages)
        for a list of the currently supported language codes.
      maxAlternatives: *Optional* Maximum number of recognition hypotheses to be
        returned. Specifically, the maximum number of
        `SpeechRecognitionAlternative` messages within each
        `SpeechRecognitionResult`. The server may return fewer than
        `max_alternatives`. Valid values are `0`-`30`. A value of `0` or `1`
        will return a maximum of one. If omitted, will return a maximum of one.
      metadata: *Optional* Metadata regarding this request.
      model: *Optional* Which model to select for the given request. Select the
        model best suited to your domain to get best results. If a model is not
        explicitly specified, then we auto-select a model based on the
        parameters in the RecognitionConfig. <table>   <tr>
        <td><b>Model</b></td>     <td><b>Description</b></td>   </tr>   <tr>

        from a phone call (typically     recorded at an 8khz sampling
        rate).</td>   </tr>   <tr>     <td><code>video</code></td>     <td>Best
        for audio that originated from from video or includes multiple
        speakers. Ideally the audio is recorded at a 16khz or greater
        sampling rate. This is a premium model that costs more than the
        standard rate.</td>   </tr>   <tr>     <td><code>default</code></td>
        <td>Best for audio that is not one of the specific audio models.
        For example, long-form audio. Ideally the audio is high-fidelity,
        recorded at a 16khz or greater sampling rate.</td>   </tr> </table>
      profanityFilter: *Optional* If set to `true`, the server will attempt to
        filter out profanities, replacing all but the initial character in each
        filtered word with asterisks, e.g. "f***". If set to `false` or omitted,
        profanities won't be filtered out.
      sampleRateHertz: Sample rate in Hertz of the audio data sent in all
        `RecognitionAudio` messages. Valid values are: 8000-48000. 16000 is
        optimal. For best results, set the sampling rate of the audio source to
        16000 Hz. If that's not possible, use the native sample rate of the
        audio source (instead of re-sampling). This field is optional for `FLAC`
        and `WAV` audio files and required for all other audio formats. For
        details, see AudioEncoding.
      speechContexts: *Optional* array of SpeechContext. A means to provide
        context to assist the speech recognition. For more information, see
        [Phrase Hints](/speech-to-text/docs/basics#phrase-hints).
      useEnhanced: *Optional* Set to true to use an enhanced model for speech
        recognition. If `use_enhanced` is set to true and the `model` field is
        not set, then an appropriate enhanced model is chosen if: 1. project is
        eligible for requesting enhanced models 2. an enhanced model exists for
        the audio  If `use_enhanced` is true and an enhanced version of the
        specified model does not exist, then the speech is recognized using the
        standard version of the specified model.  Enhanced speech models require
        that you opt-in to data logging using instructions in the [documentation
        ](/speech-to-text/docs/enable-data-logging). If you set `use_enhanced`
        to true and you have not enabled audio logging, then you will receive an
        error.

      field is optional for `FLAC` and `WAV` audio files and required for all
      other audio formats. For details, see AudioEncoding.
  
      Values:
        ENCODING_UNSPECIFIED: Not specified.
        LINEAR16: Uncompressed 16-bit signed little-endian samples (Linear PCM).
        FLAC: `FLAC` (Free Lossless Audio Codec) is the recommended encoding
          because it is lossless--therefore recognition is not compromised--and
          requires only about half the bandwidth of `LINEAR16`. `FLAC` stream
          encoding supports 16-bit and 24-bit samples, however, not all fields
          in `STREAMINFO` are supported.
        MULAW: 8-bit samples that compand 14-bit audio samples using G.711 PCMU
          /mu-law.
        AMR: Adaptive Multi-Rate Narrowband codec. `sample_rate_hertz` must be
          8000.
        AMR_WB: Adaptive Multi-Rate Wideband codec. `sample_rate_hertz` must be
          16000.
        OGG_OPUS: Opus encoded audio frames in Ogg container
          ([OggOpus](https://wiki.xiph.org/OggOpus)). `sample_rate_hertz` must
          be one of 8000, 12000, 16000, 24000, or 48000.
        SPEEX_WITH_HEADER_BYTE: Although the use of lossy encodings is not
          recommended, if a very low bitrate encoding is required, `OGG_OPUS` is
          highly preferred over Speex encoding. The [Speex](https://speex.org/)
          encoding supported by Cloud Speech API has a header byte in each
          block, as in MIME type `audio/x-speex-with-header-byte`. It is a
          variant of the RTP Speex encoding defined in [RFC
          5574](https://tools.ietf.org/html/rfc5574). The stream is a sequence
          of blocks, one block per RTP packet. Each block starts with a byte
          containing the length of the block, in bytes, followed by one or more
          frames of Speex data, padded to an integral number of bytes (octets)
          as specified in RFC 5574. In other words, each RTP header is replaced
          with a single byte containing the block length. Only Speex wideband is
          supported. `sample_rate_hertz` must be 16000.

    r"""The `Status` type defines a logical error model that is suitable for
    different programming environments, including REST APIs and RPC APIs. It is
    used by [gRPC](https://github.com/grpc). The error model is designed to be:
    - Simple to use and understand for most users - Flexible enough to meet
    unexpected needs  # Overview  The `Status` message contains three pieces of
    data: error code, error message, and error details. The error code should be
    an enum value of google.rpc.Code, but it may accept additional error codes
    if needed.  The error message should be a developer-facing English message
    that helps developers *understand* and *resolve* the error. If a localized
    user-facing error message is needed, put the localized message in the error
    details or localize it in the client. The optional error details may contain
    arbitrary information about the error. There is a predefined set of error
    detail types in the package `google.rpc` that can be used for common error
    conditions.  # Language mapping  The `Status` message is the logical
    representation of the error model, but it is not necessarily the actual wire
    format. When the `Status` message is exposed in different client libraries
    and different wire protocols, it can be mapped differently. For example, it
    will likely be mapped to some exceptions in Java, but more likely mapped to
    some error codes in C.  # Other uses  The error model and the `Status`
    message can be used in a variety of environments, either with or without
    APIs, to provide a consistent developer experience across different
    environments.  Example uses of this error model include:  - Partial errors.
    If a service needs to return partial errors to the client,     it may embed
    the `Status` in the normal response to indicate the partial     errors.  -
    Workflow errors. A typical workflow has multiple steps. Each step may
    have a `Status` message for error reporting.  - Batch operations. If a
    client uses batch request and batch response, the     `Status` message
    should be used directly inside batch response, one for     each error sub-
    response.  - Asynchronous operations. If an API call embeds asynchronous
    operation     results in its response, the status of those operations should
    be     represented directly using the `Status` message.  - Logging. If some
    API errors are stored in logs, the message `Status` could     be used
    directly after any stripping needed for security/privacy reasons.
