## 🎧 Reference Voice Guidelines (Very Important)

For best quality voice cloning:

- WAV format only  
- 10–30 seconds duration recommended  
- Single speaker  
- Clear audio, minimal background noise  
- Natural emotion (happy, calm, sad, etc.)

> ⚠️ Emotion is copied from the **reference voice**, not from the text.
