Seed Audio 1.0 Prompt Examples
公式シネマティックラジオ放送デモを含む、ポッドキャスト・広告・オーディオブック・ゲーム向けプロンプト例。
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.

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.
シンプルな TTS にはプリセットボイス
When you only need straightforward narration, select a preset voice instead of over-describing the scene.
参照入力時はボイスを空に
When using reference audio or a reference image, leave the preset voice empty — these input modes should not be combined.
参照メディアはクリーンでアクセス可能に
Use clean reference clips and publicly accessible URLs. Reference audio and image guidance cannot be used together.
