Raven-1
Raven-1 is a multimodal, real-time perceptual AI model from Tavus designed to bring emotional intelligence to artificial intelligence by interpreting human audio, visual, and temporal signals together instead of reducing communication to text alone. It unifies tone, facial expression, body language, hesitation, and contextual dynamics into a rich, unified representation of user intent and state, enabling conversational AI to understand how people communicate in real time with nuanced natural language descriptions rather than static emotion labels. It was engineered to overcome the limitations of traditional systems that rely on transcripts and limited emotion scoring by capturing subtle cues, such as emphasis, sarcasm, engagement shifts, and evolving emotional arcs, and continuously updating this understanding with low latency so responses align with the true context of the interaction.
