Tavus uses the Conversational Video Interface (CVI) as its end-to-end pipeline to bring the human layer to AI. CVI combines a Persona, which defines the AI’s behavior through layers like perception, turn-taking, and speech recognition, with a Replica, a lifelike digital human that brings the conversation to life visually.
