|
||||
|
||||

|

```
|
||||
|
||||
## 🚀 快速开始
|
||||
|
||||
### 1. 安装依赖
|
||||
|
||||
```bash
|
||||
pip install httpx
|
||||
# 或者更新所有依赖
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### 2. 最简单的使用方式
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from tts.factory import TTSEngineFactory
|
||||
|
||||
async def main():
|
||||
# 创建 CosyVoice 引擎
|
||||
engine = TTSEngineFactory.create("cosyvoice")
|
||||
|
||||
# 合成语音
|
||||
audio = await engine.synthesize(
|
||||
text="你好，这是测试",
|
||||
voice="your_speaker_id" # 替换为实际的发音人ID
|
||||
)
|
||||
|
||||
# 保存音频
|
||||
with open("output.wav", "wb") as f:
|
||||
f.write(audio.getvalue())
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
### 3. FastAPI 中使用
|
||||
|
||||
```python
|
||||
from fastapi import APIRouter, HTTPException
|
||||
from tts.factory import TTSEngineFactory
|
||||
|
||||
router = APIRouter()
|
||||
|
||||
@router.post("/tts/synthesize")
|
||||
async def synthesize(text: str, speaker_id: str):
|
||||
try:
|
||||
engine = TTSEngineFactory.create("cosyvoice")
|
||||
audio = await engine.synthesize(text=text, voice=speaker_id)
|
||||
return {"status": "success", "size": len(audio.getvalue())}
|
||||
except Exception as e:
|
||||
raise HTTPException(status_code=400, detail=str(e))
|
||||
```
|
||||
|
||||
## 📋 API 规范
|
||||
|
||||
### CosyVoice API
|
||||
|
||||
```
|
||||
POST http://192.168.1.200:8000/tts/zero_shot
|
||||
Content-Type: application/json
|
||||
|
||||
{
|
||||
"text": "要合成的文本",
|
||||
"zero_shot_spk_id": "发音人ID"
|
||||
}
|
||||
```
|
||||
|
||||
### Engine.synthesize() 方法
|
||||
|
||||
```python
|
||||
audio: BytesIO = await engine.synthesize(
|
||||
text: str, # 必需：要合成的文本
|
||||
voice: str, # 必需：zero_shot_spk_id
|
||||
language: str = "zh-CN", # 可选：语言代码
|
||||
rate: float = 1.0, # 可选：语速（暂不支持）
|
||||
pitch: float = 1.0 # 可选：音调（暂不支持）
|
||||
)
|
||||
```
|
||||
|
||||
## ⚙️ 配置
|
||||
|
||||
### 方式 1: 使用默认配置
|
||||
|
||||
```python
|
||||
engine = TTSEngineFactory.create("cosyvoice")
|
||||
# 使用默认 API 地址: http://192.168.1.200:8000/tts/zero_shot
|
||||
```
|
||||
|
||||
### 方式 2: 自定义 API 地址
|
||||
|
||||
```python
|
||||
from tts.cosyvoice_engine import CosyVoiceEngine
|
||||
|
||||
engine = CosyVoiceEngine(
|
||||
api_url="http://your_api:port/endpoint",
|
||||
timeout=30.0
|
||||
)
|
||||
```
|
||||
|
||||
### 方式 3: 环境变量配置
|
||||
|
||||
```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)
|
||||
```
|
||||
|
||||
## 🧪 测试
|
||||
|
||||
运行集成测试：
|
||||
|
||||
```bash
|
||||
python tts/test_cosyvoice.py
|
||||
```
|
||||
|
||||

|
||||
- ✓ 工厂模式创建
|
||||

|
||||
- ✓ 参数验证
|
||||
- ✓ 支持的引擎列表
|
||||
- ✓ 引擎对比

## 🔧 故障排查
|
||||
|
||||
### 问题：连接失败
|
||||
|
||||
```
|
||||
ValueError: Failed to connect to CosyVoice API
|
||||
```
|
||||
|
||||
**检查清单：**
|
||||
1. CosyVoice 服务是否运行
|
||||
2. API 地址是否正确
|
||||
3. 网络连接是否正常
|
||||
4. 防火墙设置
|
||||
|
||||
### 问题：缺少 voice 参数
|
||||
|
||||
```
|
||||
ValueError: voice (zero_shot_spk_id) is required for CosyVoice
|
||||
```
|
||||
|
||||
**解决：** 提供有效的 `voice` 参数
|
||||
```python
|
||||
audio = await engine.synthesize(text="文本", voice="valid_id")
|
||||
```
|
||||
|
||||
### 问题：httpx 未安装
|
||||
|
||||
```
|
||||
ModuleNotFoundError: No module named 'httpx'
|
||||
```
|
||||
|
||||
**解决：**
|
||||
```bash
|
||||
pip install httpx
|
||||
```
|
||||
|
||||
## 📦 依赖
|
||||
|
||||
已添加到 `requirements.txt`:
|
||||
- `httpx>=0.24.0` - 异步 HTTP 客户端
|
||||
|
||||
## 🔗 支持的引擎
|
||||
|
||||
```python
|
||||
from tts.factory import TTSEngineFactory
|
||||
|
||||
# 获取所有支持的引擎
|
||||
engines = TTSEngineFactory.get_supported_engines()
|
||||
# 返回: ['edge-tts', 'cosyvoice']
|
||||
|
||||
# 创建引擎
|
||||
engine = TTSEngineFactory.create("cosyvoice")
|
||||
```
|
||||
|
||||
## 📝 使用示例
|
||||
|
||||
### 示例 1: 基础用法
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from tts.factory import TTSEngineFactory
|
||||
|
||||
async def main():
|
||||
engine = TTSEngineFactory.create("cosyvoice")
|
||||
audio = await engine.synthesize(
|
||||
text="你好，世界",
|
||||
voice="female_standard"
|
||||
)
|
||||
|
||||
with open("hello.wav", "wb") as f:
|
||||
f.write(audio.getvalue())
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
### 示例 2: FastAPI 路由
|
||||
|
||||
```python
|
||||
from fastapi import APIRouter, HTTPException
|
||||
from tts.factory import TTSEngineFactory
|
||||
|
||||
router = APIRouter(prefix="/api/tts")
|
||||
|
||||
@router.post("/cosyvoice")
|
||||
async def synthesize_cosyvoice(text: str, speaker_id: str):
|
||||
try:
|
||||
engine = TTSEngineFactory.create("cosyvoice")
|
||||
audio = await engine.synthesize(text=text, voice=speaker_id)
|
||||
return {"status": "success"}
|
||||
except Exception as e:
|
||||
raise HTTPException(status_code=400, detail=str(e))
|
||||
```
|
||||
|
||||
### 示例 3: 自定义配置
|
||||
|
||||
```python
|
||||
from tts.cosyvoice_engine import CosyVoiceEngine
|
||||
|
||||
async def main():
|
||||
engine = CosyVoiceEngine(
|
||||
api_url="http://192.168.1.200:8000/tts/zero_shot",
|
||||
timeout=30
|
||||
)
|
||||
|
||||
try:
|
||||
audio = await engine.synthesize(
|
||||
text="自定义配置示例",
|
||||
voice="speaker_001"
|
||||
)
|
||||
finally:
|
||||
await engine.close() # 关闭连接
|
||||
```
|
||||
