PaddleSpeech
PaddleSpeech is an open-source toolkit on PaddlePaddle platform for two critical tasks in Speech - Automatic Speech Recognition (ASR) and Text-To-Speech Synthesis (TTS), with modules involving state-of-art and influential models.
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 module, and deployment. Besides, this toolkit also features at:
- Fast and Light-weight: we provide a high-speed and ultra-lightweight model that is convenient for industrial deployment.
- Rule-based Chinese frontend: our frontend contains Text Normalization (TN) 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 Research:
- Integration of mainstream models and datasets: the toolkit implements modules that participate in the whole pipeline of both ASR and TTS, and uses datasets like LibriSpeech, LJSpeech, AIShell, etc. See also model lists for more details.
- Support of ASR streaming and non-streaming data: This toolkit contains non-streaming/streaming models like DeepSpeech2, Transformer, Conformer and U2.
Let's install PaddleSpeech with only a few lines of code!
Note: The official name is still deepspeech. 2021/10/26
# 1. Install essential libraries and paddlepaddle first.
# install prerequisites
sudo apt-get install -y sox pkg-config libflac-dev libogg-dev libvorbis-dev libboost-dev swig python3-dev libsndfile1
# `pip install paddlepaddle-gpu` instead if you are using GPU.
pip install paddlepaddle
# 2.Then install PaddleSpeech.
git clone https://github.com/PaddlePaddle/DeepSpeech.git
cd DeepSpeech
pip install -e .

Alternative Installation
The base environment in this page is
- Ubuntu 16.04
- python>=3.7
- paddlepaddle==2.1.2
If you want to set up PaddleSpeech in other environment, please see the ASR installation and TTS installation documents for all the alternatives.
Quick Start
Note:
ckptfile
should be replaced by real path that represents files or folders later. Similarly,exp/default
is the folder that contains the pretrained models.
Try a tiny ASR DeepSpeech2 model training on toy set of LibriSpeech:
cd examples/tiny/s0/
# source the environment
source path.sh
# prepare librispeech dataset
bash local/data.sh
# evaluate your ckptfile model file
bash local/test.sh conf/deepspeech2.yaml ckptfile offline
For TTS, try FastSpeech2 on LJSpeech:
- Download LJSpeech-1.1 from the ljspeech official website and our prepared durations for fastspeech2 ljspeech_alignment.
- Assume your path to the dataset is
~/datasets/LJSpeech-1.1
and./ljspeech_alignment
accordingly, preprocess your data and then use our pretrained model to synthesize:
bash ./local/preprocess.sh conf/default.yaml
bash ./local/synthesize_e2e.sh conf/default.yaml exp/default ckptfile
If you want to try more functions like training and tuning, please see ASR getting started and TTS Basic Use.
Models List
PaddleSpeech ASR supports a lot of mainstream models, which are summarized as follow. For more information, please refer to ASR Models.

Tutorials
Normally, Speech SoTA gives you an overview of the hot academic topics in speech. If you want to focus on the two tasks in PaddleSpeech, you will find the following guidelines are helpful to grasp the core ideas.
The original ASR module is based on Baidu's DeepSpeech which is an independent product named DeepSpeech. However, the toolkit aligns almost all the SoTA modules in the pipeline. Specifically, these modules are
The TTS module is originally called Parakeet, and now merged with DeepSpeech. If you are interested in academic research about this function, please see TTS research overview. Also, this document is a good guideline for the pipeline components.
