Google Cloud Dialogflow V2 Client - Class InputAudioConfig (1.17.0)

Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class InputAudioConfig.

Instructs the speech recognizer how to process the audio content.

Generated from protobuf message google.cloud.dialogflow.v2.InputAudioConfig

Namespace

Google \ Cloud \ Dialogflow \ V2

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ audio_encoding int

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 for more details.
↳ language_code string

Required. The language of the supplied audio. Dialogflow does not do translations. See Language Support for a list of the currently supported language codes. Note that queries in the same session do not necessarily need to specify the same language.
↳ 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 array

A list of strings containing words and phrases that the speech recognizer should recognize with higher likelihood. See the Cloud Speech documentation for more details. This field is deprecated. Please use speech_contexts instead. If you specify both phrase_hints and speech_contexts, Dialogflow will treat the phrase_hints as a single additional SpeechContext.
↳ speech_contexts array<SpeechContext>

Context information to assist speech recognition. See the Cloud Speech documentation for more details.
↳ model string

Optional. Which Speech model to select for the given request. For more information, see Speech models.
↳ model_variant int

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.
↳ phrase_sets array

A collection of phrase set resources to use for speech adaptation.
↳ opt_out_conformer_model_migration bool

If true, 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 to Dialogflow ES Speech model migration.
