Re: Auto generated closed captions from YouTube videos and WCAG compliancy

I think the accuracy of the captions would be covered by the fact that
captions are an accessible alternative so they should convey the same
information the author intended to convey with the audio.

Unfortunately, that doesn't simply mean the caption needs to be 99% accurate
because both the number and types of errors in the caption could be
important.

To me, that says relying solely on auto captioning to conform to that part
of WCAG 2.1 is not possible. If you are going to use auto captioning to
meet WCAG 2.1, it needs to be part of a process that involves doing at least
the things that Patrick and Birkir suggest.

Maybe some day auto captioning will reach the point where we always can just
assume it is accurate enough, but I don't think we are there yet.

Just my opinion for what it is worth.

Thanks!
