Wake Word Detection

소개

This skill provides expert guidance for building offline, low-latency wake word detection systems, specifically optimized for JARVIS-style voice assistants. It emphasizes a privacy-first approach by processing audio locally and minimizing data retention to ensure user security. By following test-driven development (TDD) principles and implementing efficiency patterns like VAD preprocessing and model quantization, the skill enables developers to maintain highly accurate keyword spotting while keeping resource consumption under 5% CPU usage and 100MB of memory.
