What is Seed Audio 1.0?
Seed Audio 1.0 is a ByteDance text-to-audio model that generates natural speech and audio from prompts. It supports preset voices, optional reference audio (up to 3 clips), optional image guidance, and prompt-based control of emotion, ambience, and dialogue — going beyond basic single-voice TTS when your prompt describes a richer scene.
Preset Voice Selection
Pick from multiple preset voices for straightforward text-to-speech generation.
Reference Audio Guidance
Upload up to 3 reference clips to guide voice style. Leave preset voice empty and do not combine with image input.
Image Guidance
Use a single reference image to guide audio mood and texture. Do not combine with reference audio.
Emotional Delivery
Control emotion, tone, pacing, and atmosphere through clear, focused prompts.
Creator Workflows
Use outputs in videos, podcasts, ads, games, courses, and narration projects.
How to Use Seed Audio 1.0

- 2
Choose the audio style
Select a style such as podcast, audiobook, product ad, cinematic trailer, game dialogue, or short video voiceover.

Generate the audio, listen to the result, and adjust your prompt if you need clearer dialogue, stronger emotion, or more realistic sound effects.
- 5
Use it in your creative workflow

Seed Audio 1.0 Prompt Examples
Ready-made prompt examples — including the official cinematic radio broadcast demo — for podcasts, ads, audiobooks, games, education, and trailers.
Post-apocalyptic radio broadcast audio: an old radio studio at night, microphone static, rain hitting cracked windows, emergency lights buzzing, papers shaking from distant explosions. A tired male radio host speaks into the microphone: "If anyone can hear this, stay away from the northern bridge. The city is not safe anymore." Realistic radio voice, emotional, tense, cinematic, no music.
Create a warm podcast intro with one friendly host, soft background music, clean room tone, and a short transition sound. The host should sound confident, calm, and natural.
Generate a 20-second product ad audio scene for a premium skincare product. Include a clear female narrator, soft luxury background music, subtle bottle-opening sound, and a final brand cue.
Create a dramatic audiobook scene with two characters speaking in a rainy street at night. Add distant thunder, footsteps, emotional pauses, and low cinematic background music.
Generate fantasy game NPC dialogue in a medieval village. Include one old merchant voice, background market ambience, light crowd noise, coins, and wooden cart sounds.
Create an energetic voiceover for a 15-second TikTok-style video. Add upbeat background music, fast pacing, small whoosh transitions, and a strong ending line.
Generate a training audio scene with a narrator and a learner. The narrator explains calmly, the learner asks one question, and the background should sound like a quiet classroom.
Create a 30-second cinematic trailer audio scene for a sci-fi adventure. Include a deep narrator voice, rising orchestral music, spaceship ambience, low rumbles, and a powerful final hit.
Generate a short product demo audio for a smart kitchen appliance. Include a friendly narrator, light cooking ambience, button click sound effects, steam sounds, and cheerful background music.
Create a subtle horror ambience scene in an abandoned hotel corridor. Include quiet wind, distant door creaks, slow footsteps, low tension music, and a whisper-like narrator. Keep it suspenseful, not loud.
Generate a peaceful meditation audio with a calm narrator, slow breathing rhythm, soft nature ambience, gentle background pads, and no sudden sound effects.

Seed Audio 1.0 vs Traditional Text-to-Speech
Traditional TTS excels at clean spoken voice. Seed Audio 1.0 adds preset voices, reference audio, image guidance, and richer prompt-based narration and atmosphere.
| Feature | Traditional TTS | Seed Audio 1.0 |
|---|---|---|
| Single voice narration | Yes | Yes |
| Preset voice selection | Limited | Yes |
| Reference audio / image input | — | Yes |
| Multi-speaker dialogue | Limited | Stronger prompt-based control |
| Background music | — | Via prompt description |
| Ambience & environment | — | Via prompt description |
| Sound effects | — | Via prompt description |
| Emotional delivery | Basic to advanced | Stronger prompt-based control |
| Richer audio scenes | Limited | Typical |
| Input flexibility | Text only | Text + reference audio or image |
Traditional TTS is best for clean narration. Seed Audio 1.0 is stronger when you need preset voices, reference-guided style, image guidance, or prompts that describe mood, ambience, dialogue, and scene detail.

Best Practices for Better Seed Audio 1.0 Results
Describe the full scene, not just the voice
Instead of writing "a woman speaks about a product," describe the environment, speaker tone, music, ambience, and sound effects.
Specify the number of speakers
For dialogue, clearly define each speaker, their role, emotion, and speaking style.
Control the mood with audio words
Use words like warm, cinematic, suspenseful, energetic, calm, luxury, playful, documentary, or dramatic.
Keep prompts structured
A clear prompt with scene, speakers, music, ambience, sound effects, and duration usually works better than a vague paragraph.
Use reference audio responsibly
Reference audio can help guide style or tone, but you should only use audio you have the legal right to upload.
Use preset voice for simple TTS
When you only need straightforward narration, select a preset voice instead of over-describing the scene.
Leave voice empty with reference inputs
When using reference audio or a reference image, leave the preset voice empty — these input modes should not be combined.
Keep reference media clean and accessible
Use clean reference clips and publicly accessible URLs. Reference audio and image guidance cannot be used together.
