```

## Volume Control

Check/adjust system volume before speaking:

```bash
# Check current volume (0-100) and mute status
osascript -e "output volume of (get volume settings)"
osascript -e "output muted of (get volume settings)"

# Unmute
osascript -e "set volume without output muted"

# Set volume (0-100)
osascript -e "set volume output volume 70"
```

## Use Cases

- **提醒**: `say -v "Meijia" "會議即將開始"`
- **警告**: `say -v "Meijia" "注意，有新的緊急訊息"`

## Notes

- Runs synchronously (blocks until speech completes)
- Add `&` for async: `say "message" &`
- Works only on macOS
