## Project Introduction
py-xiaozhi is a Python-based Xiaozhi voice client, designed to learn coding and experience AI voice interaction without hardware requirements. This repository is ported from [xiaozhi-esp32](https://github.com/78/xiaozhi-esp32).

## Demo
- [Bilibili Demo Video](https://www.bilibili.com/video/BV1HmPjeSED2/#reply255921347937)

## Features
- **AI Voice Interaction**: Supports voice input and recognition, enabling smart human-computer interaction with natural conversation flow.
- **Visual Multimodal**: Supports image recognition and processing, providing multimodal interaction capabilities and image content understanding.
- **IoT Device Integration**: Supports smart home device control, enabling more IoT functions and building a smart home ecosystem.
- **Online Music Playback**: Advanced Music Player: A high-performance music player built on Pygame, supporting play/pause/stop, progress control, lyric display, and local caching, delivering a more stable and smooth listening experience.
- **Voice Wake-up**: Supports wake word activation, eliminating manual operation (disabled by default, manual activation required).
- **Auto Dialogue Mode**: Implements continuous dialogue experience, enhancing user interaction fluidity.
- **Graphical Interface**: Provides intuitive GUI with Xiaozhi expressions and text display, enhancing visual experience.
- **Command Line Mode**: Supports CLI operation, suitable for embedded devices or environments without GUI.
- **Cross-platform Support**: Compatible with Windows 10+, macOS 10.15+, and Linux systems for use anywhere.
- **Volume Control**: Supports volume adjustment to adapt to different environmental requirements with unified sound control interface.
- **Session Management**: Effectively manages multi-turn dialogues to maintain interaction continuity.
- **Encrypted Audio Transmission**: Supports WSS protocol to ensure audio data security and prevent information leakage.
- **Automatic Verification Code Handling**: Automatically copies verification codes and opens browsers during first use, simplifying user operations.
- **Automatic MAC Address Acquisition**: Avoids MAC address conflicts and improves connection stability.
- **Modular Code**: Code is split and encapsulated into classes with clear responsibilities, facilitating secondary development.
- **Stability Optimization**: Fixes multiple issues including reconnection and cross-platform compatibility.

## System Requirements
- Python version: 3.9 >= version <= 3.12
- Supported operating systems: Windows 10+, macOS 10.15+, Linux
- Microphone and speaker devices

## Read This First!
- Carefully read [项目文档](https://huangjunsen0406.github.io/py-xiaozhi/) for startup tutorials and file descriptions
- The main branch has the latest code; manually reinstall pip dependencies after each update to ensure you have new dependencies

## Upcoming Features
- [ ] **New GUI (Electron)**: Provides a more modern and beautiful user interface, optimizing the interaction experience.

## FAQ
- **Can't find audio device**: Please check if your microphone and speakers are properly connected and enabled.
- **Wake word not responding**: Check if the `USE_WAKE_WORD` setting in `config.json` is set to `true` and the model path is correct.
- **Network connection failure**: Check network settings and firewall configuration to ensure WebSocket or MQTT communication is not blocked.
- **Packaging failure**: Make sure PyInstaller is installed (`pip install pyinstaller`) and all dependencies are installed. Then re-execute `python scripts/build.py`
