Voice Flight

Voice Flight is a microphone-controlled obstacle game for FoloToy AI Passport. Make noise to give the plane lift, stay quiet to let it descend, and fly through each opening to score.

This project builds on the hardware BSP and project structure from FoloToy/ai-passport, with a new standalone voice-controlled game, gameplay logic, tests, and documentation.

Play

1. Keep the area quiet while the game performs its roughly 1.2-second microphone calibration.
2. Press OK to start.
3. Use ordinary voice volume or a gentle breath near the microphone to climb. Reduce the sound level to descend.
4. Avoid the top, bottom, and moving obstacles. Each passed obstacle adds one point.

Controls:

• OK: start, pause, resume, or retry.
• UP / DOWN while not actively flying: raise or lower microphone sensitivity.
• Hold DOWN while not actively flying: recalibrate the ambient noise floor.
• Hold OK: return to the title screen.

The best score lasts for the current power session. Gameplay intentionally uses visual feedback only because speaker output can feed back into the microphone and move the plane.

Build

The target is ESP32-C3 with ESP-IDF 5.5.3. Activate the toolchain, then run:

./tools/validate.sh --static
./tools/validate.sh --firmware

The verified installer image is written to build/FoloToy-AI-Passport-full.bin. See Build and Test for environment, flash, and recovery details.

Hardware-dependent acceptance still requires a real AI Passport: verify calibration in quiet and noisy rooms, sensitivity levels, control latency, display smoothness, and clean recovery after microphone or button initialization failure.
