The Montreal Forced Aligner is a command line utility for performing forced alignment of speech datasets using Kaldi (http://kaldi-asr.org/).
Please see the documentation http://montreal-forced-aligner.readthedocs.io for installation and usage.
If you run into any issues, please check the mailing list for fixes/workarounds or to post a new issue.
You can install MFA either entirely through conda or a mix of conda for Kaldi and Pynini dependencies and Python packaging for MFA itself
MFA is hosted on conda-forge and can be installed via:
conda install -c conda-forge montreal-forced-aligner
in your environment of choice.
If you'd like to install a local version of MFA or want to use the development set up, the easiest way is first create the dev environment from the yaml in the repo root directory:
conda env create -n mfa-dev -f environment.yml
Alternatively, the dependencies can be installed via:
conda install -c conda-forge python=3.11 kaldi librosa biopython praatio tqdm requests colorama pyyaml pynini openfst baumwelch ngram
MFA can be installed in develop mode via:
pip install -e .[dev]
You should be able to see appropriate output from mfa version
The test suite is run via tox -e py38-win or tox -e py38-unix depending on the OS, and the docs are generated via tox -e docs
