* feat: Wake up when a person is detected * fix: Solve the problem of no sound when using WakeWordInvoke * fix: Solve the problem of triggering dialogue when the person has not left * feat(vision): 优化视觉检测逻辑并增加配置接口 本次提交旨在优化视觉检测功能,使其行为更自然、更智能,并为用户提供灵活的配置选项。 主要更新包括: 1. 引入了更精细的检测状态机: - IDLE: 空闲状态,等待检测目标。 - VALIDATING: 验证状态,在检测到目标后,持续一段时间(可配置)以确认其存在,防止误触发。 - COOLDOWN: 冷却状态,在一次成功交互后进入,避免过于频繁的打扰。 2. 新增了用于配置视觉检测的 MCP 工具: - self.vision.get_detection_config: 获取当前的检测参数(阈值、冷却间隔、验证时长、目标类型)。 - self.vision.set_detection_config: 允许用户动态修改这些参数,以适应不同场景。 3. 性能优化: - 增加了配置参数的内存缓存,避免了在检测循环中对 NVS 的频繁访问。 * feat: Inference using Model 4 * feat: default inference disable * feat: version cmd change to output json * fix: fix image display * Fix include directives for esp_check and esp_app_desc --------- Co-authored-by: Spencer <love4yzp@gmail.com> Co-authored-by: Xiaoxia <terrence@tenclass.com>
An MCP-based Chatbot
Introduction
👉 Handcraft your AI girlfriend, beginner's guide【bilibili】
As a voice interaction entry, the XiaoZhi AI chatbot leverages the AI capabilities of large models like Qwen / DeepSeek, and achieves multi-terminal control via the MCP protocol.
Version Notes
The current v2 version is incompatible with the v1 partition table, so it is not possible to upgrade from v1 to v2 via OTA. For partition table details, see partitions/v2/README.md.
All hardware running v1 can be upgraded to v2 by manually flashing the firmware.
The stable version of v1 is 1.9.2. You can switch to v1 by running git checkout v1. The v1 branch will be maintained until February 2026.
Features Implemented
- Wi-Fi / ML307 Cat.1 4G
- Offline voice wake-up ESP-SR
- Supports two communication protocols (Websocket or MQTT+UDP)
- Uses OPUS audio codec
- Voice interaction based on streaming ASR + LLM + TTS architecture
- Speaker recognition, identifies the current speaker 3D Speaker
- OLED / LCD display, supports emoji display
- Battery display and power management
- Multi-language support (Chinese, English, Japanese)
- Supports ESP32-C3, ESP32-S3, ESP32-P4 chip platforms
- Device-side MCP for device control (Speaker, LED, Servo, GPIO, etc.)
- Cloud-side MCP to extend large model capabilities (smart home control, PC desktop operation, knowledge search, email, etc.)
- Customizable wake words, fonts, emojis, and chat backgrounds with online web-based editing (Custom Assets Generator)

Software
Firmware Flashing
For beginners, it is recommended to use the firmware that can be flashed without setting up a development environment.
The firmware connects to the official xiaozhi.me server by default. Personal users can register an account to use the Qwen real-time model for free.

Development Environment
- Cursor or VSCode
- Install ESP-IDF plugin, select SDK version 5.4 or above
- Linux is better than Windows for faster compilation and fewer driver issues
- This project uses Google C++ code style, please ensure compliance when submitting code
