## Installation for Chinese users
The download-site of third-lib openfst and boost may not be reached easily in China, I suggest that you can replace the download-site by:


```bash
# get the code
git clone --recursive -b linrio-patch-1 https://github.com/linrio/ctcdecode.git
cd ctcdecode
pip install .
