My problem with languages is that I’m very good at phonetics, so I can speak confidently with minimal accent as long as I know what I want to say—I’ve actually done some voice acting in languages that I don’t speak—but my comprehension is terrible. I can read French almost as fast as I read English, but can’t really follow a TV show or carry on a conversation. It’s maddening. Unfortunately, there seem to be more resources out there for people with the opposite problem: poor production but good comprehension. Anyone in a similar boat to mine who can offer advice? Is simple immersion the best approach?
