PATKIT - Phonetic Analysis ToolKIT

PATKIT provides tools for phonetic analysis of speech data. It includes a GUI for manual assessment/analysis/annotation (see picture above), command line tools for batch processing, and an API for programming your own tools.

While currently PATKIT's tools mainly work on tongue and larynx ultrasound as well as audio, in the 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, uninterpolated 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.

Getting PATKIT

Detailed instructions.

Quick start guide:

Check that PyPi finds patkit and if it does:

• Install uv.
• On the commandline run uv tool install patkit.
• Run patkit --help for instructions.
• If you want to run the example data, get the recorded_data folder from github.
  • Run patkit recorded_data/minimal in the folder where you downloaded the data and experiment from there.

Current version and development plans

See Changelog, for what's new in the current version and what's coming up.

What's included

TODO 0.15: give a quick description of included data and goodies here. TODO 1.0: Move the data elsewhere to be optionally loaded.

Contributing

Please get in touch with Pertti, if you would like to contribute to the project. All help is welcome regardless of your skill level. You can contribute by trying to use it according to instructions and reporting back when they lead you astray, proofreading docs, commenting code, testing PATKIT on a new platform, writing new functionality, writing tests for the code, roasting the code, doing UI design, contributing use cases...

Versioning

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.

For the versions available, see the tags on this repository.
