Robust yet lenient forced-aligner built on Kaldi. A tool for aligning speech with text.
There are three ways to install Gentle.
Download the pre-built Mac application. This package includes a GUI that will start the server and a browser. It only works on Mac OS.
Use the Docker image. Just run
docker run -P lowerquality/gentle. This works on all platforms supported by Docker.
Download the source code and run
./install.sh. Then run
python3 serve.pyto start the server. This works on Mac and Linux.
By default, the aligner listens at http://localhost:8765. That page has a graphical interface for transcribing audio, viewing results, and downloading data.
There is also a REST API so you can use Gentle in your programs. Here's an example of how to use the API with CURL:
curl -F "firstname.lastname@example.org" -F "email@example.com" "http://localhost:8765/transcriptions?async=false"
If you've downloaded the source code you can also run the aligner as a command line program:
git clone https://github.com/lowerquality/gentle.git cd gentle ./install.sh python3 align.py audio.mp3 words.txt
The default behaviour outputs the JSON to stdout. See
python3 align.py --help for options.
