Types

type AudioConfig 

type AudioConfig struct {
	// AudioEncoding: Required. The format of the requested audio byte
	// stream.
	//
	// Possible values:
	//   "AUDIO_ENCODING_UNSPECIFIED" - Not specified. Will return result
	// google.rpc.Code.INVALID_ARGUMENT.
	//   "LINEAR16" - Uncompressed 16-bit signed little-endian samples
	// (Linear PCM).
	// Audio content returned as LINEAR16 also contains a WAV header.
	//   "MP3" - MP3 audio.
	//   "OGG_OPUS" - Opus encoded audio wrapped in an ogg container. The
	// result will be a
	// file which can be played natively on Android, and in browsers (at
	// least
	// Chrome and Firefox). The quality of the encoding is considerably
	// higher
	// than MP3 while using approximately the same bitrate.
	AudioEncoding string `json:"audioEncoding,omitempty"`

	// Pitch: Optional 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.
	Pitch float64 `json:"pitch,omitempty"`

	// SampleRateHertz: The synthesis sample rate (in hertz) for this audio.
	// Optional.  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.
	SampleRateHertz int64 `json:"sampleRateHertz,omitempty"`

	// SpeakingRate: Optional 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.
	SpeakingRate float64 `json:"speakingRate,omitempty"`

	// VolumeGainDb: Optional 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.
	VolumeGainDb float64 `json:"volumeGainDb,omitempty"`

	// server regardless of whether the field is empty or not. This may be
	// used to include empty fields in Patch requests.

func (*VoicesListCall) IfNoneMatch 

func (c *VoicesListCall) IfNoneMatch(entityTag string) *VoicesListCall

IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

func (*VoicesListCall) LanguageCode 

func (c *VoicesListCall) LanguageCode(languageCode string) *VoicesListCall

LanguageCode sets the optional parameter "languageCode": Optional (but recommended) [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag. If specified, the ListVoices call will only return voices that can be used to synthesize this language_code. E.g. when specifying "en-NZ", you will get supported "en-*" voices; when specifying "no", you will get supported "no-*" (Norwegian) and "nb-*" (Norwegian Bokmal) voices; specifying "zh" will also get supported "cmn-*" voices; specifying "zh-hk" will also get supported "yue-*" voices.
