Offline keyword spotting & wake word engine. ONNX format, model <130KB, inference <10ms. Runs on Android, ESP32, Linux, Web. No cloud, no data usage.
Train custom wake word models with openWakeWord. A granular 13-step pipeline with compatibility patches for torchaudio 2.10+, Piper TTS, and speechbrain. Generates tiny ONNX models (~200 KB) for real-time keyword detection — like building your own "Hey Siri" trigger. WSL2/Linux + CUDA required.
Train custom wake words for Home Assistant + ESPHome (M5Stack Atom Echo, Voice PE) via a single self-driving Colab notebook. Bug-fixed wrapper around kahrendt/microWakeWord with all gotchas patched.
