Vowel sounds are often difficult for non-native speakers to pronounce. One explanation is that there are five vowel letters in English (A, E, I, O, U) but fifteen vowel sounds and there may be no clear relationship between the printed letter and its sound. Some vowels have one spelling but as many as 10 different sounds Think about these words: cough, bough, dough, rough, through, thorough – the same “ough” spelling, but six different pronunciations!
