Generatore audio AI SeedAudio
SeedAudio is ByteDance's Doubao Seed audio model for generating complete sound scenes from text and reference audio. Combine multi-role dialogue, emotion, background music, and environmental effects in a single pass for podcasts, ads, games, and narrative previews.
Built for full-scene audio, multi-role dialogue, and production-ready sound design
SeedAudio comes from ByteDance's Doubao Seed team and moves beyond classic text-to-speech. It targets finished audio scenes that combine speech, emotion, ambience, music, and effects in a single generation pass.
Scene generation
Describe a complete audio scene with dialogue, mood, and background layers. SeedAudio coordinates voices, music, and environmental sound in one pass instead of stitching clips manually.
Reference-guided extension
Use text plus reference audio to preserve timbre, extend narration, and keep speaker identity stable across longer outputs reported up to two minutes in a single run.
Core Direction
SeedAudio leans into end-to-end audio production
Public coverage positions Doubao-Seed-Audio 1.0 as a multimodal audio model rather than a narrow TTS endpoint. The practical workflow is to draft a scene quickly, refine roles and ambience, then extend with reference audio while keeping voice consistency.
Multi-role dialogue
Generate conversations with distinct speakers, emotional tone, and dialect or accent control in the same audio scene.
Full-scene layering
Combine speech, background music, and foley-style effects so the output feels closer to a mixed scene than isolated voice lines.
Multimodal inputs
Start from text instructions and reference audio to steer performance, timbre, and scene direction more precisely.

Recommended flow
A simple 3-step working pattern
Step 1
Block the audio scene
Write the scene in plain language, including speakers, emotion, pacing, and background sound.
