This smells like an LLM trying to correct the output of a speech recognition system. I said the word “racist” repeatedly and got this unedited output. You could see it changing the text momentarily after the initial recognition result, and given the way Mamaroneck sounds nothing like either of the other words I’d bet this thing was trained on news stories:
“Racist, Trump, Mamaroneck racist Trump Mamaroneck, racist racist racist racist Trump Mamaroneck”
