Hi, I am really interested in comparison of basic pronunciation differences. I am an English University teacher, well but this summer I`ve met my American cousin and I realised that I have to imagine the spelling of some words to understand her, the "r" sound was OK but sound short "o" like in word "pot" you know they pronounce "a" in some words. It was a bit hard. What about you as a native speaker? Do you feel the same difficulties with Americans?
As for Russian I could try to help now I have holidays.
