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

StepAudio 3 is StepFun’s next-generation audio model family, built to understand, generate, and interact through voice, sound, and music. The lineup includes StepAudio 3 Realtime for natural full-duplex conversation, StepAudio 3 ASR for speech recognition, StepAudio 3 TTS for speech synthesis, StepAudio 3 Gen for general-purpose audio generation, and StepAudio 3 Music for long-form music creation. Realtime is designed around a continuous listen-converse-think-act loop, understanding not only words but also hesitation, laughter, emotion, pauses, backchannels, and interruptions. It can think while speaking, reason through harder questions without breaking conversational flow, and use tools to complete tasks once it understands the user’s intent. StepAudio 3 Gen unifies zero-shot TTS, voice design, vocal generation, sound effects, music, and mixed audio generation within one framework, while StepAudio 3 Music supports text-controlled songs, instrumentals, vocal arrangement, and more.
