Tools for processing speech data. While currently these tools mainly work on tongue and larynx ultrasound as well as audio, in future, the toolkit will include facilities for processing other kinds of articulatory data. The first two tools to be implemented are Optical Flow and Pixel Difference.
Optical Flow tracks local changes in ultrasound frames and estimates the flow field based on these.
Pixel Difference and Scanline Based Pixel Difference -- work on raw, uniterpolated data and produce measures of change over the course of a recording. How they work is explained in Chapter 3 of Pertti Palo's PhD thesis.
There will be incremental 0.x releases until the codebase reaches milestones for version 1.0 (See Roadmap). While this notice is here in the main branch, that update is not yet complete. In the meanwhile, if you wish to try SATKIT or contribute to the code or as a beta tester, please contact Pertti for instructions.
With version 1.0 getting closer a lot of the instructions below are outdated. More up-to-date information can be found in the Documentation. See Roadmap for updates on progress towards 1.0.
Current version is 0.9.0. See Release notes, for what's new.
Download the repository to either a subdirectory of the project you want to use the tools on or a suitable place that you then add to your $PYTHONPATH.
SATKit should run with the following or more recent (see the .yml files in
environments/ for a more complete list):
- Python 3.10
- PyQt5 v5.12
- MatPlotLib 3.5
- NumPy 1.22
- OpenCV 4.5
- SciPy 1.3
- praat-textgrids 1.3
A handy way of getting MatPlotLib, NumPy, and SciPy is to get them as part of the Anaconda distribution. Using mamba as the environment manager when creating virtual environments is recommended because conda may not manage to solve the dependencies and may refuse to install anything.
Note: If you decide to use Anaconda, you should install any additional packages you are getting with mamba (or conda) before installing praat-textgrids with pip as the final step of setting up a virtual environment.
For OF you will need in addition:
- DIPY 1.5
For processing lip videos:
- Scikit-video 1.1
An installation through pypi is in the works. Do get in touch if you would like to test it.
A downloadable executable will hopefully also become reality. Do get in touch if you would like to develop it.
To install all of the above and create a conda environment to run SATKIT in
first install anaconda from the link above. Then install mamba because anaconda
is unlikely to solve the dependencies correctly. Do this on the command line
with: conda install mamba -n base -c conda-forge
After you've (possibly forked and) cloned the repository from github with your
favourite git tool, cd into the repository root. There you should find the file
called satkit_devel_conda_env.yaml and satkit_stable_conda_env.yaml.
If you are not going to work on SATKIT itself, you should setup the stable
environment. To install the required packages and create the environment, run:
mamba env create -f satkit_stable_conda_env.yaml
Activate the environment with conda activate satkit-stable and the basics are
set up. If you want to have an editable install (changing code in the repo
changes behaviour of the installed SATKIT immediately) run finally pip install -e . or python3 -m pip install --editable . if you prefer being explicit.
If you plan on working on SATKIT, run the commands
mamba env create -f satkit_devel_conda_env.yaml and
conda activate satkit-devel instead of the ones above.
See MANIFEST.markdown for a description of the contents.
There are three small datasets included in the distribution. You can
run tests on them with the test script pd_test.py. Currently the
following work and produce a new spaghetti_plot.pdf and a transcript
in [method_name].log.
python satkit.py tongue_data_1_1The first example directory contains recordings with all files present while the second is intentionally missing some files. The latter case should therefore produce warnings in the resulting log. Running without the exclusion list specified should produce a plot with a couple more curves in it.
The routines to deal with a directory structure like that of test2
are yet to be implemented.
Proper testing is yet to be implemented.
Please, read the docs and get in touch with Pertti, if you would like to contribute to the project.
We use SemVer for versioning under the rules as set out by PEP 440 with the additional understanding that releases before 1.0 (i.e. current releases at time of writing) have not been tested in any way.
