1. Turn Audio on and allow the mic.
2. Teach — hold each button (don’t tap): hum steadily, clap 2–3 times, then stay silent.
3. Listen — the app guesses hum / clap / silent and plays a different sound for each (tone · clap burst · quiet).
Need at least 5 examples per class. If everything sounds the same, tap Clear and teach again with louder, clearer gestures.
