Often time when I look up a pronunciation video, it's for a language I'm learning and I have a vague idea of how the word is supposed to sound, but not sure on things like tonality and stress.

So, if I were to look up how to say "ramen", I might not know if it's supposed to be ra-MEN or RA-men, but I'd know it's wrong if they say it like "r-amen".
