**PaddleSpeech** 是基于飞桨 [PaddlePaddle](https://github.com/PaddlePaddle/Paddle) 深度学习开源框架平台上的一个开源模型库，用于语音和音频中的各种关键任务的开发，包含大量前沿和有影响力的模型，一些典型的应用示例如下：
##### 语音识别

<div align = "center">
<table style="width:100%">
  <thead>
    <tr>
      <th> 输入音频  </th>
      <th width="550"> 识别结果  </th>

  </thead>
  <tbody>
   <tr>

      </td>
      <td >I knocked at the door on the ancient side of the building.</td>
    </tr>
    <tr>
      <td align = "center">

      </td>
      <td>我认为跑步最重要的就是给我带来了身体健康。</td>
    </tr>
    
  </tbody>
</table>

</div>

## 安装

我们强烈建议用户在 **Linux** 环境下，*3.7* 以上版本的 *python* 上安装 PaddleSpeech。这种情况下安装 `paddlespeech` 只需要一条 `pip` 命令:
```python
pip install paddlepaddle paddlespeech
```
目前为止，对于 **Mac OSX、 LiNUX** 支持声音分类、语音识别、语音合成和语音翻译四种功能，**Windows** 下暂不支持语音翻译功能。 想了解更多安装细节，可以参考[安装文档](./docs/source/install_cn.md)。

## 快速开始

安装完成后，开发者可以通过命令行快速开始，改变 `--input` 可以尝试用自己的音频或文本测试。

**声音分类**     
```shell
paddlespeech cls --input input.wav
```
**语音识别**
```shell
paddlespeech asr --lang zh --input input_16k.wav
```
**语音翻译** (English to Chinese)
```shell
paddlespeech st --input input_16k.wav
```
**语音合成** 
```shell
paddlespeech tts --input "你好，欢迎使用百度飞桨深度学习框架！" --output output.wav
```
> Note: 如果需要训练或者微调，请查看[语音识别](./docs/source/asr/quick_start.md)， [语音合成](./docs/source/tts/quick_start.md)。

## 模型列表

PaddleSpeech 支持很多主流的模型，并提供了预训练模型，详情请见[模型列表](./docs/source/released_model.md)。

PaddleSpeech 的**语音转文本** 包含声学模型、语言模型和语音翻译, 详情如下：
