    /**
     Streaming speech synthesis of the text in the body parameter.

          Synthesizes text to spoken audio, returning the synthesized audio stream as an array of bytes. Identical to the
     `GET` method but passes longer text in the body of the request, not with the URL. Text size is limited to 5 KB.
     (For the `audio/l16` format, you can optionally specify `endianness=big-endian` or `endianness=little-endian`; the
     default is little endian.)   If a request includes invalid query parameters, the service returns a `Warnings`

    /**
     Queries details about a word in a custom voice model.

     Returns the translation for a single word from the custom model with the specified `customization_id`. The output
     shows the translation as it is defined in the model. You must use credentials for the instance of the service that
     owns a model to query information about its words.   **Note:** This method is currently a beta release.
