Optional. Iftrue, Dialogflow returnsSpeechWordInfoinStreamingRecognitionResultwith information about the recognized speech words, e.g. start and end time offsets. If false or unspecified, Speech doesn't return any word-level information.
↳ phrase_hints
array
Optional. A list of strings containing words and phrases that the speech recognizer should recognize with higher likelihood. Seethe Cloud Speech documentationfor more details.
↳ model
string
Optional. Which Speech model to select for the given request. For more information, seeSpeech models.
Optional. Iffalse(default), recognition does not cease until the client closes the stream. Iftrue, 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.
Configuration of barge-in behavior during the streaming of input audio.
↳ opt_out_conformer_model_migration
bool
Iftrue, the request will opt out for STT conformer model migration. This field will be deprecated once force migration takes place in June 2024. Please refer toDialogflow CX Speech model migration.
