Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class TextToSpeechSettings.
Instructs the speech synthesizer on how to generate the output audio content.
Generated from protobuf message google.cloud.dialogflow.v2.TextToSpeechSettings
Namespace
Google \ Cloud \ Dialogflow \ V2
Methods
__construct
Constructor.
Parameters
Name
Description
data
array
Optional. Data for populating the Message object.
↳ enable_text_to_speech
bool
Optional. Indicates whether text to speech is enabled. Even when this field is false, other settings in this proto are still retained.
↳ output_audio_encoding
int
Required. Audio encoding of the synthesized audio content.
↳ sample_rate_hertz
int
Optional. 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).
Optional. Indicates whether text to speech is enabled. Even when this field
is false, other settings in this proto are still retained.
Returns

bool
setEnableTextToSpeech
Optional. Indicates whether text to speech is enabled. Even when this field
is false, other settings in this proto are still retained.
