Types

type AudioConfig 

type AudioConfig struct {
	// Required. The format of the requested audio byte stream.
	AudioEncoding AudioEncoding `` /* 147-byte string literal not displayed */
	// 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 `protobuf:"fixed64,2,opt,name=speaking_rate,json=speakingRate" json:"speaking_rate,omitempty"`
	// 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 `protobuf:"fixed64,3,opt,name=pitch" json:"pitch,omitempty"`
	// 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 `protobuf:"fixed64,4,opt,name=volume_gain_db,json=volumeGainDb" json:"volume_gain_db,omitempty"`
	// 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 int32 `protobuf:"varint,5,opt,name=sample_rate_hertz,json=sampleRateHertz" json:"sample_rate_hertz,omitempty"`
