We share Net together.

Highlights

• Production first and production ready: The core design principle, WeNet provides full stack production solutions for speech recognition.
• Accurate: WeNet achieves SOTA results on a lot of public speech datasets.
• Light weight: WeNet is easy to install, easy to use, well designed, and well documented.

Install

Install python package

pip install git+https://github.com/wenet-e2e/wenet.git

Command-line usage (use -h for parameters):

wenet --language chinese audio.wav

Python programming usage:

import wenet

model = wenet.load_model('chinese')
result = model.transcribe('audio.wav')
print(result['text'])

Please refer python usage for more command line and python programming usage.

Install for training & deployment

• Clone the repo

git clone https://github.com/wenet-e2e/wenet.git

• Install Conda: please see https://docs.conda.io/en/latest/miniconda.html
• Create Conda env:

conda create -n wenet python=3.10
conda activate wenet
conda install conda-forge::sox

• Install CUDA: please follow this link, It's recommended to install CUDA 12.1
• Install torch and torchaudio, It's recomended to use 2.2.2+cu121:

pip install torch==2.2.2+cu121 torchaudio==2.2.2+cu121 -f https://download.pytorch.org/whl/torch_stable.html

• Install CANN: please follow this link to install CANN toolkit and kernels.

• Install WeNet with torch-npu dependencies:

pip install -e .[torch-npu]

• Related version control table:

• Install other python packages

pip install -r requirements.txt
pre-commit install  # for clean and tidy code

• Frequently Asked Questions (FAQs)

# If you encounter sox compatibility issues
RuntimeError: set_buffer_size requires sox extension which is not available.
# ubuntu
sudo apt-get install sox libsox-dev
# centos
sudo yum install sox sox-devel
# conda env
conda install  conda-forge::sox

Build for deployment

Optionally, if you want to use x86 runtime or language model(LM), you have to build the runtime as follows. Otherwise, you can just ignore this step.

# runtime build requires cmake 3.14 or above
cd runtime/libtorch
mkdir build && cd build && cmake -DGRAPH_TOOLS=ON .. && cmake --build .

Please see doc for building runtime on more platforms and OS.

Discussion & Communication

You can directly discuss on Github Issues.

For Chinese users, you can also scan the QR code on the left to follow our official account of WeNet. We created a WeChat group for better discussion and quicker response. Please scan the personal QR code on the right, and the guy is responsible for inviting you to the chat group.

Acknowledge

1. We borrowed a lot of code from ESPnet for transformer based modeling.
2. We borrowed a lot of code from Kaldi for WFST based decoding for LM integration.
3. We referred EESEN for building TLG based graph for LM integration.
4. We referred to OpenTransformer for python batch inference of e2e models.
