xiaozhi-esp32-server
本项目为xiaozhi-esp32提供后端服务，帮助您快速搭建ESP32设备控制服务器。Backend service for xiaozhi-esp32, helps you quickly build an ESP32 device control server.
The xiaozhi-esp32-server is a comprehensive backend service that connects AI assistants to ESP32 hardware devices through MCP protocol support. Designed for the xiaozhi-esp32 open-source hardware project, it enables voice-controlled smart device interactions by integrating speech recognition (ASR), large language models (LLM), text-to-speech (TTS), and IoT control capabilities. The server supports both MQTT+UDP and WebSocket protocols, offers streaming ASR/TTS for faster response times, and includes features like voiceprint recognition, knowledge base integration, and a web-based management console. It serves as an MCP integration point that allows AI agents to communicate with and control physical ESP32-powered devices through standardized protocols.
