The ESP32-S3 dev board runs a TensorFlow Lite Micro speech model that constantly listens through the INMP441 I2S microphone. When you say the wake word, it lights an LED and sounds a piezo buzzer, all within the chip’s low-power always-on pipeline. Perfect for demonstrating how edge AI replaces cloud-dependent voice assistants in home automation, industrial monitoring, or assistive technology projects.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eBy the end of this project, you’ll have a standalone keyword spotter that responds to your voice in real time. The system processes audio on-device, classifies the input as wake word or background, and toggles outputs instantly.
