Class InputAudioConfig (2.22.0)

InputAudioConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Instructs the speech recognizer how to process the audio content.


Required. Audio encoding of the audio content to process.
sample_rate_hertz int
Required. Sample rate (in Hertz) of the audio content sent in the query. Refer to `Cloud Speech API documentation
language_code str
Required. The language of the supplied audio. Dialogflow does not do translations. See `Language Support
enable_word_info bool
If true, Dialogflow returns SpeechWordInfo in StreamingRecognitionResult with 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 MutableSequence[str]
A list of strings containing words and phrases that the speech recognizer should recognize with higher likelihood. See `the Cloud Speech documentation
speech_contexts MutableSequence[]
Context information to assist speech recognition. See `the Cloud Speech documentation
model str
Which Speech 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 InputAudioConfig. If enhanced speech model is enabled for the agent and an enhanced version of the specified model for the language does not exist, then the speech is recognized using the standard version of the specified model. Refer to `Cloud Speech API documentation
Which variant of the [Speech model][] to use.
single_utterance bool
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.
disable_no_speech_recognized_event bool
Only used in Participants.AnalyzeContent and Participants.StreamingAnalyzeContent. If false and recognition doesn't return any result, trigger NO_SPEECH_RECOGNIZED event to Dialogflow agent.
enable_automatic_punctuation bool
Enable automatic punctuation option at the speech backend.
