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. -
From Sourse:
Install Prerequisites
sudo apt-get install build-essential
sudo apt-get install gfortran
sudo apt install python-minimal
Then download the source code and run ./install.sh
. Then run python3 serve.py
to start the server.
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 "audio=@audio.mp3" -F "transcript=@words.txt" "http://localhost:8765/transcriptions?async=false"
If you've downloaded the source code you can also run the aligner as a command line program:
python3 align.py audio.mp3 words.txt
The default behaviour outputs the JSON to stdout. See python3 align.py --help
for options.
