ESP32 WebRTC Conversational Voice Agent

This talk walks through the journey of bringing conversational AI to one of the smallest devices yet — an ESP32 microcontroller. Using an M5Stack AtomS3R and Atomic Echo Base, I integrated my ElevenLabs voice clone with the Pipecat AI framework and WebRTC for real-time, low-latency audio streaming. The talk covers the challenges of working with constrained hardware, why LLMs aren’t a magic bullet here, and how open-source contributions from the Pipecat community made this possible. Attendees will see how a tiny embedded device can become a fully conversational voice agent.
