A Python client library for Xiaozhi AI assistant
Project description
Xiaozhi Client
这是一个用于连接小智AI助手的Python客户端库。它提供了简单的接口来进行语音对话和文本交互。
源码安装
git clone https://github.com/Eric0308/xiaozhi-client.git
cd xiaozhi-client
conda create -n xiaozhi-client python=3.10 -y
conda activate xiaozhi-client
pip install -e .
python examples/simple_client.py
pip 安装
conda create -n xiaozhi-client python=3.10 -y
conda activate xiaozhi-client
pip install xiaozhi-client
python examples/simple_client.py
快速开始
这是一个基础的文本对话示例:
import asyncio
import sys
from xiaozhi_client import XiaozhiClient, ClientConfig
from concurrent.futures import ThreadPoolExecutor
async def main():
client = XiaozhiClient(ClientConfig(ws_url="ws://localhost:8000",))
client.on_tts_end = lambda msg: print("\n请输入消息(输入q退出):")
# 创建输入循环
executor = ThreadPoolExecutor(max_workers=1)
loop = asyncio.get_event_loop()
print("\n请输入消息(输入q退出):")
try:
await client.connect()
while True:
message = await loop.run_in_executor(executor, sys.stdin.readline)
message = message.strip()
if message.lower() == 'q':
break
if message:
await client.send_txt_message(message)
# 等待音频播放完成
while client.is_playing.is_set():
await asyncio.sleep(0.1)
finally:
await client.close()
asyncio.run(main())
完整示例代码请参考 simple_client.py
语音对话示例
这是一个基础的语音对话示例:
import asyncio
from xiaozhi_client import XiaozhiClient, ClientConfig, AudioConfig
async def start_voice_chat(
ws_url: str = "ws://localhost:8000",
sample_rate: int = 16000,
channels: int = 1
):
"""启动语音对话"""
config = ClientConfig(ws_url=ws_url)
audio_config = AudioConfig(sample_rate=sample_rate, channels=channels)
client = XiaozhiClient(config, audio_config)
async def on_tts_end(msg):
print("\n[系统] 继续聆听中... (q:退出)")
client.resume_voice_input()
client.on_tts_end = on_tts_end
try:
await client.connect()
# 启动语音输入
await client.start_voice_input()
print("[系统] 开始对话... (q:退出)\n")
# 命令处理循环
while True:
cmd = await asyncio.get_event_loop().run_in_executor(None, input, "")
cmd = cmd.strip().lower()
if cmd == 'q': break
finally:
await client.close()
print("\n[系统] 程序已退出")
asyncio.run(start_voice_chat())
完整示例代码请参考 audio_chat.py
特性
- WebSocket连接管理
- 音频编解码(Opus格式)
- 支持实时语音对话
- 支持文本消息交互
- 内置设备标识和认证
- 支持不同的语音识别模式
配置项
ClientConfig
- ws_url: WebSocket服务器地址
- device_token: 设备认证token
- enable_token: 是否启用token认证
- protocol_version: 协议版本(默认1)
AudioConfig
- sample_rate: 采样率(默认16000)
- channels: 声道数(默认1)
- frame_size: 帧大小(默认960)
- frame_duration: 帧时长(默认20ms)
- format: 音频格式(默认"opus")
支持的消息类型
语音识别
# 开始监听
{
"type": "listen",
"state": "start",
"mode": "auto" # auto/manual/realtime
}
# 停止监听
{
"type": "listen",
"state": "stop"
}
TTS状态回调
{
"type": "tts",
"state": "start|stop|sentence_start",
"text": "要说的文本" # 仅在 sentence_start 时存在
}

开发说明
音频处理
客户端发送和接收的音频数据都使用Opus编码:
- 采样率:16000Hz
- 声道数:1(单声道)
- 帧大小:960样本/帧
- 帧时长:20ms
错误处理
客户端会自动处理连接断开等错误:
- WebSocket连接断开时会触发重连
- 音频解码错误会被捕获并记录
- 网络错误会抛出相应异常
依赖
- websockets==10.4
- opuslib==3.0.1
- numpy==2.2.3
- sounddevice==0.5.1
- loguru==0.7.3
- pyaudio==0.2.14
协议文档
完整的协议文档请参考API文档。主要包括:
- 设备认证
- 音频流协议
- 消息类型定义
- 错误处理机制
