I'm from Finland, so my mother language isn't English. In Finnish we pronounce actually the same way we write (for example we pronounce Finland's capital Helsinki like Hell-sin-key and kiikari (binocular) little bit like key-car-e). I only knew that in English you write differently than you pronounce, but i thought that it works like A is E, T is V, B is D and so on. so i thought that people who speak english just change letters in their head and then pronounce it like people in finland. I'm not sure when I figured out how it really works but at least at school when I started to study English. I hope you understand my explanation :)
