As a speaker of Scandinavian languages, literally none of the vowels in English map correctly to how we pronounce the same vowels. Several of the English vowels are diphthongs, which we spell out with double vowels. Like eng. "i" is our "ai", eng. "a" is our "ei" - "a bridge" is translated to "ei bro", where the articles are pronounced exactly the same. Or the Scottish word for home, "hame", is pronounced exactly like we say the same word, "heim".
