Instructs the speech recognizer how to process the audio content.
Required. Sample rate (in Hertz) of the audio content sent in
the query. Refer to Cloud Speech API documentation
<https://cloud.google.com/speech-to-text/docs/basics>__ for
more details.
Optional. A list of strings containing words and phrases that
the speech recognizer should recognize with higher likelihood.
See the Cloud Speech documentation
<https://cloud.google.com/speech-to-text/docs/basics#phrase-
hints>__ for more details.
Optional. If false (default), recognition does not cease
until the client closes the stream. If true, the
recognizer will detect a single spoken utterance in input
audio. Recognition ceases when it detects the audio's voice
has stopped or paused. In this case, once a detected intent is
received, the client should close the stream and start a new
request with a new stream as needed. Note: This setting is
relevant only for streaming methods. Note: When specified,
InputAudioConfig.single_utterance takes precedence over
StreamingDetectIntentRequest.single_utterance.
