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.
