# PaddlePaddle Speech toolkit
*DeepSpeech* is an open-source implementation of end-to-end Automatic Speech Recognition engine, with [PaddlePaddle ](https://github.com/PaddlePaddle/Paddle ) platform. Our vision is to empower both industrial application and academic research on speech recognition, via an easy-to-use, efficient, samller and scalable implementation, including training, inference & testing module, and deployment.
## Features
See [feature list ](docs/source/asr/feature_list.md ) for more information.
