Introduction

The xiaozhi-esp32-server is an open-source backend service designed to complement the xiaozhi-esp32 hardware project. Developed by Professor Siyuan Liu's Team at South China University of Technology, this project allows you to build a sophisticated ESP32 device control server with integrated AI functionalities. It supports a wide array of features, including MQTT+UDP, WebSocket protocols, MCP access points, and advanced voiceprint recognition, making it ideal for creating intelligent human-machine interaction systems.

Installation

Setting up your xiaozhi-esp32-server is straightforward, with options tailored to different needs. The project provides two primary deployment methods:

  • Simplified Installation: Ideal for lower-spec environments, focusing on intelligent dialogue, IoT, MCP, and visual perception, with data stored in configuration files.
  • Full Module Installation: Offers a complete experience, including intelligent dialogue, IoT, MCP access points, voiceprint recognition, visual perception, OTA, and a smart control console, storing data in a database.

Both methods support Docker and local source code deployment. Detailed deployment documentation and video tutorials are available in the official repository to guide you through the process.

For comprehensive instructions, please refer to the Deployment Documentation in the project's README.

Examples

The xiaozhi-esp32-server empowers your ESP32 devices with a range of intelligent capabilities. Here are some examples of what you can achieve:

  • Responsive Voice Control: Experience rapid response times for voice commands.
