star history
This project provides a complete open-source voice assistant platform combining custom hardware and software. The ESP32-S3-based PCB serves as a drop-in replacement for a Google Nest Mini, handling audio capture locally while offloading AI processing to a server. The server-side code leverages Whisper for speech-to-text, LLMs for generating responses, and TTS engines for audio output. Example applications demonstrate querying messaging systems, controlling smart home devices via Home Assistant, and managing notes or memos through conversational commands.
