I was watching an old Twilight Zone episode yesterday, which starred a very young Dennis Hopper as a neo-Nazi who meets up with a shadowy benefactor who turns out to be ... (three guesses, eh?) Hitler, of course. And, of course, this Hitler character was speaking English with some sort of not-that-great German accent.

It made me wonder ... I've seen film with audio of Hitler's speeches, and he was certainly an amazing orator. I wonder what the real Hitler would have sounded like if he were speaking English, or some other language. So, tl;dr, did Hitler speak any other languages? If so, is there any surviving audio/video of him doing so?
