DialogflowSynthesizeSpeechConfig
Configuration of how speech should be synthesized.
Add the following line to your scenario code to use the interface:
require(Modules.AI);
Props
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
| undefined
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
| undefined
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 not set (0.0), defaults to the native 1.0 speed. Any other values < 0.25 or > 4.0 return an error.
volumeGainDb
volumeGainDb: number
| undefined
Optional. Volume gain (in dB) of the normal native volume supported by the specific voice, in the range [-96.0, 16.0]. If not set, or set to a value of 0.0 (dB), plays at normal native signal amplitude. A value of -6.0 (dB) plays at approximately half the amplitude of the normal native signal amplitude. A value of +6.0 (dB) plays at approximately twice the amplitude of the normal native signal amplitude. We strongly recommend not to exceed +10 (dB) as there is usually no effective increase in loudness for any value greater than that.
