I have recently thought about teaching myself some foreign accents. Naturally, I figured, I could speak with a German accent (being German, that's not too hard), and it worked - sort of. What I am really interested in, though, are other accents, for example a Russian one.
What would be the best way to teach myself the proper usage of such an accent (I know, nothing is worse than a badly imitated accent) - are there any websites around you could recommend or books that might prove useful?
Any help would be appreciated!
