Yeah. I also notice that Google Translate's guess at pronunciation frequently has errors, and that IS a LLM.

Someone further downthread said it appears to have about 80% accuracy on a short sentence, which means if you're not already at a level of skill where you can verify, then it's going to teach you the wrong pronunciations constantly. When studying languages myself, I find that learning the wrong pronunciation for something is annoyingly sticky, and unlearning takes more effort than learning something correctly the first time.
