Seed Audio

Seed Audio unifies three ByteDance Seed research lines — Seed-TTS, Seed-Music, and SeedFoley — into a single AI audio generation tool. From one text prompt, it produces lifelike speech with zero-shot voice cloning and emotion/accent control, original music composed to match a mood or genre, or cinematic sound effects and foley synced to a scene. Output renders as studio-quality MP3 in seconds. Free to try, with paid plans starting around $119.9/year. Seed Audio is an independent platform and is not affiliated with or endorsed by ByteDance.
