How to Use Seed Audio 1.0 for AI Voice Assistants and Companions

Five Features to Build First
| Feature | Why users care | First version |
|---|---|---|
| Character greeting | Users should immediately hear who the assistant is | Generate 3 tones and let users choose |
| Story snippet | Works for kids stories, bedtime, and audio drama | Start with 30-60 second samples |

Why Not Just Use Standard TTS?
Standard TTS is good when you need clean reading. Seed Audio 1.0 is better when the output needs performance intent: character, emotion, laughter, pauses, atmosphere, and pacing can all be written into the prompt.
For AI voice products, that means:
- companions can sound more present and less mechanical
- story apps can generate short scenes instead of flat narration
- character chats can test personas, not only voices
- creator tools can turn greetings, voice packs, and short audio content into repeatable features
How to Test It
Do not start by rebuilding your whole realtime voice stack. Start narrow:
- Open Seed Audio 1.0 on EvoLink.
- Create or reuse an EvoLink API key.
- Choose one scene, such as an AI companion greeting.
- Generate 3 versions from the same script.
- Track plays, saves, regenerations, and shares.
- If users respond, expand to stories, meditation, persona packs, or batch audio.
When Not to Use It
| Poor fit | Better option |
|---|---|
| Ultra-low-latency realtime chat | Keep a lightweight TTS route |
| Simple system messages | Use standard TTS or prebuilt audio |
| Every reply must speak immediately | Use Seed Audio 1.0 only for premium moments |
| Strict SSML behavior | Use a route that explicitly supports SSML |
