Class VoiceSelectionParams (1.1.3)

Description of which voice to use for speech synthesis.

Optional. The preferred gender of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and [name][google.cloud.dialogflow.v2beta1.Vo iceSelectionParams.name]. Note that this is only a preference, not requirement. If a voice of the appropriate gender is not available, the synthesizer should substitute a voice with a different gender rather than failing the request.
