Types for Google Cloud Texttospeech v1beta1 API¶
- class google.cloud.texttospeech_v1beta1.types.AdvancedVoiceOptions(mapping=None, *, ignore_unknown_fields=False, **kwargs)[source]¶
Bases:
proto.message.MessageUsed for advanced voice options.
- class google.cloud.texttospeech_v1beta1.types.AudioConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)[source]¶
Bases:
proto.message.MessageDescription of audio data to be synthesized.
- audio_encoding¶
Required. The format of the audio byte stream.
- speaking_rate¶
Optional. Input only. Speaking rate/speed, in the range [0.25, 4.0]. 1.0 is the normal native speed supported by the specific voice. 2.0 is twice as fast, and 0.5 is half as fast. If unset(0.0), defaults to the native 1.0 speed. Any other values < 0.25 or > 4.0 will return an error.
- Type
- pitch¶
Optional. Input only. Speaking pitch, in the range [-20.0, 20.0]. 20 means increase 20 semitones from the original pitch. -20 means decrease 20 semitones from the original pitch.
- Type
- volume_gain_db¶
Optional. Input only. Volume gain (in dB) of the normal native volume supported by the specific voice, in the range [-96.0, 16.0]. If unset, or set to a value of 0.0 (dB), will play at normal native signal amplitude. A value of -6.0 (dB) will play at approximately half the amplitude of the normal native signal amplitude. A value of +6.0 (dB) will play at approximately twice the amplitude of the normal native signal amplitude. Strongly recommend not to exceed +10 (dB) as there’s usually no effective increase in loudness for any value greater than that.
- Type
- sample_rate_hertz¶
Optional. The synthesis sample rate (in hertz) for this audio. When this is specified in SynthesizeSpeechRequest, 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), unless the specified sample rate is not supported for the encoding chosen, in which case it will fail the request and return [google.rpc.Code.INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT].
- Type
- effects_profile_id¶
Optional. Input only. An identifier which selects ‘audio effects’ profiles that are applied on (post synthesized) text to speech. Effects are applied on top of each other in the order they are given. See audio profiles for current supported profile ids.
- Type

Required. The language (and potentially also the region) of the voice expressed as a BCP-47 language tag, e.g. “en-US”. This should not include a script tag (e.g. use “cmn-cn” rather than “cmn-Hant-cn”), because the script will be inferred from the input provided in the SynthesisInput. The TTS service will use this parameter to help choose an appropriate voice. Note that the TTS service may choose a voice with a slightly different language code than the one selected; it may substitute a different region (e.g. using en-US rather than en-CA if there isn’t a Canadian voice available), or even a different language, e.g. using “nb” (Norwegian Bokmal) instead of “no” (Norwegian)”.
- Type

The name of the voice. If both the name and the gender are not set, the service will choose a voice based on the other parameters such as language_code.
- Type
- ssml_gender¶
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.
- custom_voice¶
The configuration for a custom voice. If [CustomVoiceParams.model] is set, the service will choose the custom voice matching the specified configuration.
- voice_clone¶
Optional. The configuration for a voice clone. If [VoiceCloneParams.voice_clone_key] is set, the service will choose the voice clone matching the specified configuration.
