Do we have any unit testing covering this? Based on the line that's not covered in this PR, I'm guessing there is not. It would be really important to add at least minimal testing.

[joanise]

Good except we need to exercise this code in CI.

I played with it a little bit. It generated a text-grid file. I was able to open it using PRAAT.

side node: I did not look at all the finer details of the text-grid file yet... but good to go for a first release!

Thanks all! You're right @joanise - I've made an issue
