You could also study linguistics! I'm not sure what type of jobs that would actually lead to, perhaps teaching or linguistics research?

I remember seeing someone on TV (I think, hopefully it wasn't a fiction show!) that studied dialects in the US, and was able to help people with amnesia figure out what part of the country they were from, based on their accent and word choice! Hmm, not sure how big the market is for a job like that - but there ARE people who study things like that, like how accents change throughout the country, and why some people say "soda" and some say "pop" and some say "coke".

Can you *do* the accents too (aside from recognizing them)? If so, that opens you up to not just acting, but dialect coaching. Some people hire coaches to help get rid of an undesirable accent, and actors might use a coach to help gain an accent for a part.

There's also teaching your native language to newcomers to your country (if you can pick up enough of their language, it would help you communicate better with them), and just teaching languages in general.

Very cool... I love languages myself, though I don't pick them up as easily as you do. Good luck with it!
