What is Seed Audio 1.0?
Seed Audio 1.0 is ByteDance's all-in-one audio generation model, introduced in 2026 as the next step in the company's Seed family of voice and audio research. Instead of only reading text aloud, Seed Audio 1.0 produces a complete soundscape — the spoken line and the world around it — from a single written prompt.
That is the big shift from traditional text-to-speech. A classic TTS engine gives you one flat voice. Seed Audio 1.0 can stage several characters in conversation, give each a distinct voice and emotion, score the moment with background music, and layer in sound effects and ambience — all generated together in one pass so everything stays in sync.
You can also guide the result with your own audio. Seed Audio 1.0 supports zero-shot voice cloning from a short reference clip and multilingual output, so the same model can localize a script into another language while keeping a consistent voice. The result is closer to a finished audio production than a raw line of speech.
What people make with Seed Audio 1.0
A few of the audio projects creators can sketch with Seed Audio 1.0 — from scripted scenes and localized narration to image-led sound design and reference-matched voices.
Cinematic radio drama
Describe a short scene and let Seed Audio 1.0 voice the characters, add room tone, weather and a music bed — a full audio moment from one prompt.
Multilingual narration
Localize a tutorial or product explainer into another language while keeping a natural accent and a consistent narrator voice across every version.
Image-led sound design
Give Seed Audio 1.0 a picture as a cue and shape ambience, material sounds or a branded mood when words alone would be too vague.
Reference-matched voiceover
Provide a short, approved reference clip and let Seed Audio 1.0 carry that voice and tone through a longer generated voiceover.

What makes Seed Audio 1.0 different
Seed Audio 1.0 is built for prompt-directed audio production, so a single description can carry voices, music and sound design at the same time.
Multi-character dialogue
Stage a conversation between several speakers in one generation, each with a distinct voice, pacing and emotion instead of a single flat narrator.
Zero-shot voice cloning
Match a voice from a short reference clip, so a consented sample can carry through narration, characters or a recurring brand voice.
Music, effects and ambience
Generate background music, sound effects and environmental ambience together with speech, producing a finished scene rather than an isolated track.
Multilingual and cross-lingual
Produce speech in many languages with natural pronunciation, and even mix languages inside one piece for localized or international content.
Emotion and style control
Direct tone, mood, accent and delivery from the prompt — calm documentary, tense thriller, upbeat ad read or anything in between.
Longer, consistent audio
Generate extended audio of up to around two minutes per request while keeping each voice steady and recognizable across the whole clip.
Create with Seed Audio 1.0 in four steps
Shape your idea in plain language first, then refine the voices, references and mood until the scene sounds the way you imagined it.
Describe the scene
Write what you want to hear: who is speaking, the mood, the pacing, and any music, effects or background you have in mind.
Add a voice reference
Optionally attach a short reference clip to clone a voice, or point Seed Audio 1.0 at an image to guide the sound when a description is hard to put into words.
Set the tone and language
Choose the emotion, accent and language, and decide whether you want a single narrator or a full cast of characters.
Generate and refine
Listen back, then adjust the prompt or references and regenerate until the dialogue, music and ambience land together.

Tips for better Seed Audio 1.0 results
- Be specific: name the speakers, the setting, the mood and the pacing instead of asking only for high-quality audio.
- Describe the non-speech world too — music style, ambience and key sound effects — so the whole scene is generated together.
- Use a clean, short reference clip with clear rights when you want to clone or match a voice; noisy samples make the result harder to control.
- For multilingual work, state the target language and accent so pronunciation stays natural in every version.
- Direct emotion with plain words like calm, urgent, warm or playful, and adjust one thing at a time when you regenerate.
- Only clone voices you have permission to use, and disclose AI-generated audio wherever your audience or platform expects it.
