Via the easy-to-use, efficient, flexible and scalable implementation, our vision is to empower both industrial application and academic research, including training, inference & testing modules, and deployment process. To be more specific, this toolkit features at:
- **Ease of Use**: low barries to install, and [CLI ](#quick-start ) is available to quick-start your journey.
- **Align to the State-of-the-Art**: we provide high-speed and ultra-lightweight models, and also cutting edge technology.
- **Rule-based Chinese frontend**: our frontend contains Text Normalization and Grapheme-to-Phoneme (G2P, including Polyphone and Tone Sandhi). Moreover, we use self-defined linguistic rules to adapt Chinese context.
- **Varieties of Functions that Vitalize both Industrial and Academia**:
- *Implementation of critical audio tasks*: this toolkit contains audio functions like Audio Classification, Speech Translation, Automatic Speech Recognition, Text-to-Speech Synthesis, etc.
- *Integration of mainstream models and datasets*: the toolkit implements modules that participate in the whole pipeline of the speech tasks, and uses mainstream datasets like LibriSpeech, LJSpeech, AIShell, CSMSC, etc. See also [model list ](#model-list ) for more details.
- *Cascaded models application*: as an extension of the typical traditional audio tasks, we combine the workflows of the aforementioned tasks with other fields like Natural language processing (NLP) and Computer Vision (CV).
## Installation
We strongly recommend our users to install PaddleSpeech in *Linux* with *python>=3.7* and *paddlepaddle>=2.2.0* , where `paddlespeech` can be easily installed with `pip` :
```python
pip install paddlespeech
```
If you want to set up in other environment, please see the [installation ](./docs/source/install.md ) for all the alternatives.
## Quick Start
Developers can have a try of our models with [PaddleSpeech Command Line ](./paddlespeech/cli/README.md ). Change `--input` to test your own audio/text.
**Audio Classification**
```shell
paddlespeech cls --input input.wav
```
**Automatic Speech Recognition**
```shell
paddlespeech asr --lang zh --input input_16k.wav
```
**Speech Translation** (English to Chinese)
(not support for Windows now)
```shell
paddlespeech st --input input_16k.wav
```
**Text-to-Speech**
```shell
paddlespeech tts --input "你好,欢迎使用百度飞桨深度学习框架!" --output output.wav
```
- web demo for Text to Speech is integrated to [Huggingface Spaces ](https://huggingface.co/spaces ) with [Gradio ](https://github.com/gradio-app/gradio ). See Demo: https://huggingface.co/spaces/akhaliq/paddlespeech
If you want to try more functions like training and tuning, please have a look at [Speech-to-Text Quick Start ](./docs/source/asr/quick_start.md ) and [Text-to-Speech Quick Start ](./docs/source/tts/quick_start.md ).
## Model List
PaddleSpeech supports a series of most popular models. They are summarized in [released models ](./docs/source/released_model.md ) and attached with available pretrained models.
**Speech-to-Text** contains *Acoustic Model* and *Language Model* , with the following details:

## Tutorials
Normally, [Speech SoTA ](https://paperswithcode.com/area/speech ), [Audio SoTA ](https://paperswithcode.com/area/audio ) and [Music SoTA ](https://paperswithcode.com/area/music ) give you an overview of the hot academic topics in the related area. To focus on the tasks in PaddleSpeech, you will find the following guidelines are helpful to grasp the core ideas.

The TTS module is originally called [Parakeet ](https://github.com/PaddlePaddle/Parakeet ), and now merged with DeepSpeech. If you are interested in academic research about this function, please see [TTS research overview ](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/docs/source/tts#overview ). Also, [this document ](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/tts/models_introduction.md ) is a good guideline for the pipeline components.
