Did something happen to YouTube subtitles in the past few months?

I’ve been watching YouTube with subtitles for years and while they’ve never been perfect I’ve started to notice some very strange issues with them recently which did not used to occur.

The most recent example I’ve seen was from a woodworking video where the word size was subtitled as “siiz”. I’ve also noticed things like random capitalization happening more often, like “sorry for not Uploading recently” or “thanks For watching”.

Are they using a new algorithm for auto-subtitles maybe?
