What Is Seed Audio? Seed Audio is a comprehensive suite of AI-powered audio generation technologies originally developed by ByteDance's research team. It brings together the most advanced capabilities in speech synthesis, voice cloning, speech recognition, and music generation — all accessible through a simple online interface.
At the core of Seed Audio is Seed-TTS, a family of large-scale autoregressive text-to-speech models capable of generating speech that is virtually indistinguishable from natural human voice. Alongside it, Seed-ASR provides state-of-the-art automatic speech recognition trained on over 20 million hours of audio data, supporting Mandarin, 13 Chinese dialects, English, and 6 additional languages with remarkable accuracy across various accents.
The suite also includes Seed-Music for AI-powered music composition with fine-grained style control, and Seed-VC for zero-shot voice conversion that can transform any voice to sound like another. Together, these technologies represent a new generation of audio AI — one where professional-grade audio production is available to everyone, not just studios with expensive equipment.
Powerful Features for Every Audio Need From voice cloning to music composition, Seed Audio delivers professional-grade audio AI tools in your browser.
Zero-Shot Voice Cloning Clone any voice from just 3 seconds of reference audio. Seed Audio's neural voice model captures speaker identity, tone, and cadence with remarkable fidelity — no training data required.
Emotion & Style Control Go beyond flat text-to-speech. Control vocal emotions like happiness, sadness, anger, and excitement, plus styles such as whisper, broadcast, and conversational tone.
Multilingual Support Generate natural speech in 20+ languages including English, Chinese, Japanese, Korean, Spanish, French, and German. Seed-ASR also understands 13 Chinese dialects and diverse English accents.
Real-Time Processing Experience sub-100ms time-to-first-audio latency. Seed Audio's optimized inference engine delivers near-instant results, making it ideal for live applications and interactive voice agents.
AI Music Composition Create original songs and instrumentals with Seed-Music. Control style through text prompts, audio references, or musical scores. Edit lyrics and melodies directly in generated audio.
Voice Conversion Transform any voice recording into a different voice while preserving the original speech content, rhythm, and emotion. Seed-VC supports both speaking and singing voice conversion.
