klumw/wakeword ? reverse-engineered prompt

Build me a simple ESP32 S3 wake word project that listens through an I2S microphone and detects the word “computer” by default. I want it to be ready to flash on an ESP32 S3 DevKitC 1, with the onboard LED turning red when the keyword is detected so I can see it working right away.

Keep it easy to swap in a different model later, since I may want to train my own keyword too. Use the existing Edge Impulse model if that’s already included, and make sure the project builds cleanly with ESP IDF. If anything needs a current setup step or newer docs, look it up online and keep the instructions simple. Also add a short README style run through for wiring the mic and building the firmware so I can get it working fast.
