## 简介

RapidTTS 是一个轻量级文本转语音工具，面向本地快速推理。当前默认后端是导出为 ONNX 的 MeloTTS。

## 特性

- 支持 MeloTTS ONNX 推理
- 支持中文、英文和中英混合文本
- 默认模型自动下载，并使用 SHA256 校验
- 提供命令行工具：下载模型、检查安装、文本合成
- 提供 Python API，便于集成到应用中

## 安装

```bash
pip install rapidtts
```

## 快速使用

命令行合成：

```bash
rapidtts text "你好，RapidTTS" outputs/1.wav
```

Python 调用：

```python
from rapidtts import RapidTTS, SynthesisRequest, TTSModel

tts = RapidTTS(model=TTSModel.MELO_ONNX)
resp = tts.synthesize(SynthesisRequest(text="你好，RapidTTS"))
resp.save("outputs/1.wav")
```
