  PaddleSpeech is an open-source all-in-one speech toolkit. It aims at
facilitating the development and research of speech processing technologies by
providing an easy-to-use command-line interface and a simple code structure.
This paper describes the design philosophy and core architecture of
PaddleSpeech to support several essential speech-to-text and text-to-speech
tasks. PaddleSpeech achieves competitive or state-of-the-art performance on
various speech datasets and implements the most popular methods. It also
provides recipes and pretrained models to quickly reproduce the experimental
results in this paper. PaddleSpeech is publicly avaiable at
https://github.com/PaddlePaddle/PaddleSpeech.
