 *                                         language tag, e.g. "en-US". This should not include a script tag (e.g. use
 *                                         "cmn-cn" rather than "cmn-Hant-cn"), because the script will be inferred
 *                                         from the input provided in the SynthesisInput.  The TTS service
 *                                         will use this parameter to help choose an appropriate voice.  Note that
 *                                         the TTS service may choose a voice with a slightly different language code
 *                                         than the one selected; it may substitute a different region
 *                                         (e.g. using en-US rather than en-CA if there isn't a Canadian voice
 *                                         available), or even a different language, e.g. using "nb" (Norwegian
 *                                         Bokmal) instead of "no" (Norwegian)".
 * @param int    $audioConfigAudioEncoding The format of the audio byte stream.
