The English alphabet has five vowels, a, e, i, o and u, but it has about 15 main vowel sounds. For some learners this is one of the most difficult aspects of American English to master. Speakers of languages with fewer vowel sounds are likely to speak English using only the same number of sounds that exist in their native language. Sometimes they do not even hear the distinction between certain sounds in English. Consequently, non-native speakers might pronounce “hill” and “heal” the same way. Similarly, the words sell and sale, or cup, cop, and cap may also sound the same when spoken by a non-native speaker.
