Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class OutputAudioConfig.
Instructs the speech synthesizer on how to generate the output audio content.
If this audio config is supplied in a request, it overrides all existing
text-to-speech settings applied to the agent.
Generated from protobuf message google.cloud.dialogflow.v2.OutputAudioConfig
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 synthesized audio content.
↳ sample_rate_hertz
int
The synthesis sample rate (in hertz) for this audio. If not provided, then the synthesizer will use the default sample rate based on the audio encoding. If this is different from the voice's natural sample rate, then the synthesizer will honor this request by converting to the desired sample rate (which might result in worse audio quality).
Configuration of how speech should be synthesized.
getAudioEncoding
Required. Audio encoding of the synthesized audio content.
Returns
