InputAudioConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)Instructs the speech recognizer how to process the audio content.
Attributes
| Name | Description |
| audio_encoding |
google.cloud.dialogflow_v2.types.AudioEncoding
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 |
Sequence[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 |
Sequence[google.cloud.dialogflow_v2.types.SpeechContext]
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 |
| model_variant |
google.cloud.dialogflow_v2.types.SpeechModelVariant
Which variant of the [Speech model][google.cloud.dialogflow.v2.InputAudioConfig.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. |
