Introduction

The open-source xiaozhi-esp32 project on GitHub unlocks new possibilities. By leveraging ESP32-S3's capabilities and integrating APIs from models like DeepSeek, it enables localized AI voice chat. We compiled with English firmware, UNIHIKER K10 transforms into a responsive smart terminal supporting multi-turn dialogue, wake-word detection, and real-time translation.
This synergy of hardware and open-source innovation lowers barriers for AI development.
With intuitive interfaces and efficient edge computing, developers can prototype voice assistants, educational tools, or smart home solutions effortlessly. The future of edge AI starts here.
xiaozhi-esp32 is an open-source ESPIDF project, since the configuration process of ESPIDF is a bit tedious, we have compiled an English version of the xiaozhi firmware for you to flash directly.
