I still occasionally sound out words (incorrectly) when I stumble on a word that I finally realize I've gotten wrong in my head. Like I'll know the word, know what it means, but have imagined the wrong pronunciation in my head, only to have it suddenly dawn on me that "Hey, that synonym for this word you know that sounds a bit different, what if it's aactually the same word". Then I'll go look it up in a dictionary, realize I still don't know pronunciation guides, type it into Google or whatever to get audio, and confirm, yup, I'm a dumbass I've been thinking those are two different words for decades.

This happens to me about once every other month. Millions of words, I don't expect it'll ever stop happening.

Bonus points when the word is like only 6-7 characters long, feel extra dumb those months :P
