+# CosyVoice 配置模板
+
+## .env 文件配置示例
+
+将以下内容添加到项目的 `.env` 文件中：
+
+```env
+# CosyVoice API 配置
+COSYVOICE_API_URL=http://192.168.1.200:8000/tts/zero_shot
+COSYVOICE_TIMEOUT=30
+
+# TTS 引擎选择 (可选)
+TTS_ENGINE=cosyvoice  # 或 edge-tts
+```
+
+## config/app.py 配置示例
+
+添加以下代码到配置文件中：
+
+```python
+from pydantic_settings import BaseSettings
+from typing import Optional
+
+class CosyVoiceSettings(BaseSettings):
+    """CosyVoice 配置"""
+    api_url: str = "http://192.168.1.200:8000/tts/zero_shot"
+    timeout: float = 30.0
+    
+    class Config:
+        env_prefix = "COSYVOICE_"
+
+
+class Settings(BaseSettings):
+    """应用程序设置"""
+    # ... 其他设置 ...
+    
+    # TTS 设置
+    default_tts_engine: str = "cosyvoice"  # 默认使用 cosyvoice
+    cosyvoice: CosyVoiceSettings = CosyVoiceSettings()
+    
+    class Config:
+        env_file = ".env"
+```
+
+## 应用程序初始化示例
+
+在 `main.py` 中初始化 CosyVoice：
+
+```python
+from fastapi import FastAPI
+from tts.factory import TTSEngineFactory
+from config.app import settings
+
+app = FastAPI()
+
+@app.on_event("startup")
+async def startup():

+## CosyVoice 引擎集成指南
+
+本文档说明如何在项目中使用 CosyVoice 引擎进行语音合成。
+
+### 前置条件
+
+1. 已部署本地 CosyVoice API 服务
+2. API 地址：`http://192.168.1.200:8000/tts/zero_shot`
+3. 确保依赖已安装：`httpx`
+
+### 快速开始
+
+#### 方式 1: 使用工厂模式创建引擎
+
+```python
+import asyncio
+from tts.factory import TTSEngineFactory
+
+async def main():
+    # 创建 CosyVoice 引擎实例
+    engine = TTSEngineFactory.create("cosyvoice")
+    
+    # 合成语音
+    text = "你好，这是 CosyVoice 合成的语音。"
+    audio = await engine.synthesize(
+        text=text,
+        voice="your_speaker_id"  # 替换为实际的 speaker ID
+    )
+    
+    # 保存音频
+    with open("output.wav", "wb") as f:
+        f.write(audio.getvalue())
+
+asyncio.run(main())
+```
+
+#### 方式 2: 直接使用 CosyVoice 引擎
+
+```python
+import asyncio
+from tts.cosyvoice_engine import CosyVoiceEngine
+
+async def main():
+    # 创建引擎实例，可以自定义 API 地址和超时时间
+    engine = CosyVoiceEngine(
+        api_url="http://192.168.1.200:8000/tts/zero_shot",
+        timeout=30.0
+    )
+    
+    try:
+        # 合成语音
+        text = "你好，这是测试文本。"
+        audio = await engine.synthesize(
+            text=text,
+            voice="female_standard_speaker"
+        )
+        
+        # 保存或处理音频
+        with open("output.wav", "wb") as f:
+            f.write(audio.getvalue())
+    
+    finally:
+        # 关闭连接
+        await engine.close()
+
+asyncio.run(main())
+```
+
+### API 参数说明
+
+#### 合成接口 (`synthesize`)
+
+**必需参数：**
+- `text` (str): 要合成的文本
+- `voice` (str): 发音人 ID (`zero_shot_spk_id`)
+
+**可选参数：**
+- `language` (str): 语言代码，默认 "zh-CN"
+- `rate` (float): 语速，默认 1.0（暂不支持）
+- `pitch` (float): 音调，默认 1.0（暂不支持）
+
+**返回值：**
+- `BytesIO`: 包含音频数据的字节流对象
+
+**异常：**
+- `ValueError`: 如果 `voice` 参数为空，或 API 返回错误
+- `httpx.RequestError`: 网络连接错误
+
+### CosyVoice API 请求示例
+
+```bash
+curl -X POST "http://192.168.1.200:8000/tts/zero_shot" \
+  -H "Content-Type: application/json" \
+  -d {
+    "text": "你好，世界",
+    "zero_shot_spk_id": "female_standard_speaker"
+  }
+```
+
+### 配置 CosyVoice
+
+如果需要修改 API 地址或超时时间，可以：
+
+1. **环境变量配置** (推荐)
+```python
+import os
+from tts.cosyvoice_engine import CosyVoiceEngine
+
+api_url = os.getenv("COSYVOICE_API_URL", "http://192.168.1.200:8000/tts/zero_shot")
+timeout = float(os.getenv("COSYVOICE_TIMEOUT", "30"))
+
+engine = CosyVoiceEngine(api_url=api_url, timeout=timeout)
+```
+
+2. **配置文件方式** (参考 `config/app.py`)
+```python
+from tts.cosyvoice_engine import CosyVoiceEngine
+
+class CosyVoiceConfig:
+    API_URL = "http://192.168.1.200:8000/tts/zero_shot"
+    TIMEOUT = 30.0
+
+engine = CosyVoiceEngine(**CosyVoiceConfig().__dict__)
+```
+
+### FastAPI 集成示例
+
+在 API 路由中使用 CosyVoice：
+
+```python
+from fastapi import APIRouter, HTTPException
+from tts.factory import TTSEngineFactory
+
+router = APIRouter(prefix="/api/v1/tts", tags=["tts"])
+
+@router.post("/cosyvoice/synthesize")
+async def synthesize_with_cosyvoice(text: str, speaker_id: str):
+    """
+    使用 CosyVoice 合成语音
+    
+    Args:
+        text: 要合成的文本
+        speaker_id: 发音人 ID
+    
+    Returns:
+        音频文件内容
+    """
+    try:
+        engine = TTSEngineFactory.create("cosyvoice")
+        audio = await engine.synthesize(text=text, voice=speaker_id)
+        
+        return {
+            "status": "success",
+            "audio_size": len(audio.getvalue()),
+            "content_type": "audio/wav"
+        }
+    except ValueError as e:
+        raise HTTPException(status_code=400, detail=str(e))
+    except Exception as e:
+        raise HTTPException(status_code=500, detail="TTS synthesis failed")
+```
+
+### 发音人 ID 参考
+
+常见的发音人 ID 示例（需根据实际部署调整）：
+
+- `female_standard_speaker`: 女性标准发音
+- `female_gentle_speaker`: 女性温柔发音
+- `male_standard_speaker`: 男性标准发音
+- `male_gentle_speaker`: 男性温柔发音
+
+具体的发音人 ID 应该根据您部署的 CosyVoice 服务配置。
+
+### 故障排查
+
+#### 问题 1: "Failed to connect to CosyVoice API"
+
+**原因：** 
+- CosyVoice 服务未运行
+- API 地址配置错误
+- 网络连接问题
+
+**解决方案：**
+```bash
+# 检查服务是否运行
+curl http://192.168.1.200:8000/tts/zero_shot -X POST -d "{\"text\":\"test\",\"zero_shot_spk_id\":\"test\"}"
+
+# 检查网络连接
+ping 192.168.1.200
+```
+
+#### 问题 2: "voice (zero_shot_spk_id) is required for CosyVoice"
+
+**原因：** 没有提供 `voice` 参数
+
+**解决方案：** 确保调用 `synthesize()` 时提供了 `voice` 参数
+
+```python
+audio = await engine.synthesize(
+    text="测试",
+    voice="valid_speaker_id"  # 提供有效的发音人 ID
+)
+```
+
+#### 问题 3: HTTP 错误 (400, 500 等)
+
+**原因：** API 响应错误
+
+**解决方案：**
+- 检查文本格式是否正确
+- 验证 speaker_id 是否有效
+- 查看 CosyVoice 服务日志获取详细错误信息
+
+### 性能优化
+
+1. **连接重用**：使用工厂模式创建引擎实例可以重用 HTTP 连接
+2. **超时配置**：根据网络情况调整 timeout 参数
+3. **异步处理**：使用异步接口避免阻塞

+# CosyVoice 集成实现总结
+
+## 概述
+
+成功实现了对自部署 CosyVoice API 的支持。该实现遵循现有的 TTS 架构模式，通过工厂模式和抽象基类提供了统一的接口。
+
+## 实现内容
+
+### 1. 核心引擎实现
+
+**文件**: `tts/cosyvoice_engine.py`
+
+- ✓ 实现 `TTSEngine` 抽象基类的所有方法
+- ✓ 使用 `httpx` 异步库调用 CosyVoice API
+- ✓ 支持自定义 API 地址和超时时间
+- ✓ 完善的错误处理和日志记录
+- ✓ 提供 `close()` 方法管理 HTTP 连接
+
+**关键方法**:
+```python
+async def synthesize(
+    text: str,
+    voice: str,  # zero_shot_spk_id
+    language: str = "zh-CN",
+    rate: float = 1.0,
+    pitch: float = 1.0
+) -> BytesIO
+```
+
+### 2. 工厂模式集成
+
+**文件**: `tts/factory.py`
+
+- ✓ 添加 `COSYVOICE` 到 `TTSEngineType` 枚举
+- ✓ 在 `_engines` 字典中注册 `CosyVoiceEngine`
+- ✓ 保持与现有 `EdgeTTSEngine` 兼容
+
+**使用方式**:
+```python
+# 方式 1: 使用字符串
+engine = TTSEngineFactory.create("cosyvoice")
+
+# 方式 2: 使用枚举
+engine = TTSEngineFactory.create(TTSEngineType.COSYVOICE)
+```
+
+### 3. 模块导出
+
+**文件**: `tts/__init__.py`
+
+- ✓ 导出 `CosyVoiceEngine` 类
+- ✓ 更新模块文档说明
+
+### 4. 依赖管理
+
+**文件**: `requirements.txt`
+
+- ✓ 添加 `httpx` 异步 HTTP 客户端库
+
+### 5. 示例代码
+
+**文件**: `tts/examples.py`
+
+- ✓ 添加示例 5: `example_cosyvoice()`
+- ✓ 添加示例 6: `example_cosyvoice_custom_api()`
+
+### 6. 测试套件
+
+**文件**: `tts/test_cosyvoice.py`
+
+- ✓ 工厂模式创建测试
+- ✓ 直接实例创建测试
