Score: 7.0/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 6)

This project turns a cheap ESP32 Audio Kit into a Bluetooth handset that connects a phone to a voice AI agent via WebRTC and a local Go bridge. It innovatively combines classic Bluetooth HFP, real-time audio streaming, and a self-hosted voice API bridge, enabling a low-cost, privacy-controllable voice agent device.

Target audience: embedded devs, iot enthusiasts, voice-ai developers
