GoogleCloudDialogflowV2InputAudioConfig class

Instructs the speech recognizer how to process the audio content.


GoogleCloudDialogflowV2InputAudioConfig.fromJson(Map _json)


audioEncoding String
Required. Audio encoding of the audio content to process. Possible string values are: [...]
read / write
enableWordInfo 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.
read / write
hashCode int
The hash code for this object. [...]
read-only, inherited
languageCode 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.
read / write
model String
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 for more details.
read / write
modelVariant String
Which variant of the Speech model to use. Possible string values are: [...]
read / write
phraseHints List<String>
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.
read / write
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
sampleRateHertz int
Required. Sample rate (in Hertz) of the audio content sent in the query. Refer to Cloud Speech API documentation for more details.
read / write
singleUtterance 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.
read / write
speechContexts List<GoogleCloudDialogflowV2SpeechContext>
Context information to assist speech recognition. See the Cloud Speech documentation for more details.
read / write
