Hello, I'm the maintainer of praatio, a library that your code depends on. I have a new version that I intend to release soon. It includes some breaking changes.

If you don't feel like upgrading, you should be able to change
praatio
to
praatio<5.0
in your requirements.txt file

I'm sorry for the headache. If you have any questions, please let me know.

Also, cool project!
