[Lingtyp] Praat script for automatically segmenting vowels?

[Ian Maddieson]

Dear Cat,

Reading your description of what you want to do I’m wondering it if is necessary to use an aligner,
as it would seem that a simple marking of the vowel center is all you need (although a script to 
extract formant values would no doubt be useful). There is no need to do a complete segmentation.
Are you working with isolated words or is all your data continuous speech? How many tokens of
each vowel do you aim to measure? And how dense is the vowel space in this language?

I’d add that it is also necessary to check that the formant extraction is reliable, which requires
a pretty hands-on examination of the data.

Two programs that quickly come to mind are the Praat plug-in EasyAlign and the Montreal Forced Aligner. Either one of these can autosegment down to the phone level. I've never tried EasyAlign, but I'd guess as a plug-in it would be fairly straightforward. I have used the MFA, and will admit there is some amount of work that goes into using it... at least for what I'm using it for.
