Reads the moment
A worried caller gets a calm, steady voice. Good news sounds like good news. The agent adjusts its delivery to what is being said.
Expressive voice
The same words, said the way the moment needs.
Revti agents speak with the newest expressive voice models. Scroll, drag or use the arrow keys to turn the dial and see one sentence take on a different tone.
