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.
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.
