TextGrid file isn't according to spec

[skol101]

Could you check if .textgrid file produced is according to spec?

i'm using this https://github.com/nltk/nltk_contrib/blob/95d1806e2f4e89e960b76a685b1fba2eaa7d5142/nltk_contrib/textgrid.py to test generated textgrid files.

Hi we use praatio to save the textgrid. In most cases it should not give any problems.
I have tested the textgrid files using Praat. They can be opened and shows up normally.
What are the error messages?

Yes, you're correct. I initially used Textgrid(file) method which results in error. After using .load(file) method everything is fine. Though I wonder why lab files (created using KALDI) are showing timestamps in ms, and praat in seconds?

I think the time stamp by Kaldi might not be in ms. It looks like the number of samples to me. Maybe you can verify this by dividing it by the sampling rate to see if it's the case. If this is ms, the sounds are way too long.

Cheers, I'll check your suggestion.
