Voice

A flow has one listening setup, stt, and one speaking setup, tts. Each is a service plus that provider's settings. Change them on the flow's Voice tab, save setups to reuse on Voices, or try a change for a single call from Settings for this test on the Test tab.

#Flow-wide extras

These sit on the flow (Behaviour tab), not inside stt or tts. From code, send them in runtime:

voice-isolationnumber

Background noise suppression. Removes background noise from the caller’s audio. From 0 to 1. Default: 0.

grain-voiceboolean

Natural texture. Adds a faint grain so the voice sounds less synthetic. Default: true.

grain-levelnumber

Texture strength. How strong the texture is. Only used when grain-voice is on. From 0 to 0.15. Default: 0.025.
