I agree it's heavily accent dependent and I suspect the original compiler wasn't that aware of non-mainstream US accents.

It's interesting that many of these are only the same (initially at least) if you've been sloppy/ignorant in your pronunciation and then those become baked in ways of saying something.

We're due to get a lot more of these given how often you hear influencers guessing at what to me seem fairly mainstream pronunciations!

These are often a way that TTS systems slip up most obviously. A lockdown project I tinkered with several years back was a small (traditional) LM that had been fed with tagged examples and could thus predict fairly well the best sense for a particular case. It made a huge difference to perceived quality. Now of course, many TTS cope with this fairly well but you still hear the off slip up!
