Instructs the speech recognizer how to process the audio content.
Generated from protobuf message google.cloud.dialogflow.v2.InputAudioConfig
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 |
↳ 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<Google\Cloud\Dialogflow\V2\SpeechContext>
Context information to assist speech recognition. See the Cloud Speech documentation for more details. |
↳ 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. |
↳ model_variant |
int
Which variant of the Speech model to use. |
↳ single_utterance |
bool
If |
↳ disable_no_speech_recognized_event |
bool
Only used in Participants.AnalyzeContent and Participants.StreamingAnalyzeContent. If |

getSingleUtterance
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.
| Returns | |
|---|---|
| Type | Description |
