What is Seed Audio

Seed Audio is an AI-powered audio generation platform that brings together ByteDance's most advanced audio technologies — Seed-TTS, Seed-ASR, Seed-Music, and Seed-VC — into a single, easy-to-use online service.

The Seed Audio Suite

At its core, Seed Audio combines four breakthrough AI models:

• Seed-TTS — large-scale autoregressive text-to-speech that generates speech virtually indistinguishable from human voice, with zero-shot voice cloning from just 3 seconds of reference audio.
• Seed-ASR — automatic speech recognition trained on over 20 million hours of audio data, supporting Mandarin, 13 Chinese dialects, English, and 6 additional languages.
• Seed-Music — AI music composition with fine-grained style control through text prompts, audio references, and musical scores.
• Seed-VC — zero-shot voice conversion that transforms any voice to sound like another while preserving original content, rhythm, and emotion.

Key Capabilities

1. Zero-Shot Voice Cloning — clone any voice from just 3 seconds of reference audio, no training required.
2. Emotion & Style Control — generate speech with specific emotions (happy, sad, excited) and styles (whisper, broadcast, conversational).
3. Multilingual Support — natural speech generation in 20+ languages with accurate accent handling.
4. Real-Time Processing — sub-100ms time-to-first-audio latency for live applications.
5. Music Composition — create original songs and instrumentals with AI-powered arrangement.
