ESP32 Voice Control with AI (No Cloud Needed!)

Control your ESP32 with just your voice – no cloud, no internet, pure on-device AI!
In this video, we’ll build a keyword spotting model with Edge Impulse and run it locally on an ESP32 (ESPID or any ESP32 + microphone). Say “red” or “white” and watch the LEDs react instantly.
