DialogflowSynthesizeSpeechConfig

Configuration of how speech should be synthesized.

Properties

effectsProfileId

effectsProfileId: string[]

Optional. 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.

pitch

pitch: number

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.

speakingRate

speakingRate: number

Type of the result message.

voice

Optional. The desired voice of the synthesized audio.

volumeGainDb

volumeGainDb: number

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. We strongly recommend not to exceed +10 (dB) as there's usually no effective increase in loudness for any value greater than that.
