Hell, it even sucks at accented English. A friend turned me onto the UK series Taskmaster, which is available on YouTube. I turn on captions/subtitles as a matter of habit, and the auto-generated captions for that show are atrocious.
Yes, that show includes a variety of UK English, Irish, Scottish, and Welsh accents, but... damn, it's bad.
