About

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.

About

Realtime TTS-2 from Inworld AI is a new generation of voice model built for real-time conversation: a voice model that feels as human as it sounds. It hears the full audio of an exchange, picks up the user’s tone, pacing, and emotional state, then takes voice direction in plain English, the way developers prompt an LLM. Instead of generating speech in isolation, it listens to prior turns of the exchange, so tone and pacing carry forward, and the same line can land differently after a joke than after bad news. Voice Direction lets developers steer delivery like a director would steer a voice actor, using natural-language descriptions rather than fixed emotion presets or sliders. Inline nonverbals like [sigh], [breathe], and [laugh] can be placed inside the text, and the model renders them as audio events. Realtime TTS-2 preserves one voice identity across more than 100 languages, including mid-utterance language switches.
