10 Those references mean that pronunciation is very important in learning foreign language especially English language. People will understand what EFL learners are going to say if they can pronounce the words clearly rather than their grammar. When they can pronounce or mention the words clearly, people will understand their goals no matter how bad their grammar is. Learning pronunciation is not only learning how to mention the words, but also learning to pronounce diphthongs correctly. The English diphthongs are a part of linguistics and pronunciation. Linguistics has some branches such as phonetics, phonology, stress, placement, diphthongs, morphology, syntax, and other aspects. This research focuses on diphthongs only. 2. Pronunciation According to the Oxford Dictionary, the word ‘pronounce’ is defined as ‘make the sound of a word or part of a word in the correct or a particular way’. Pronunciation can be defined as a way in which a language is spoken, especially the way in which it is generally accepted or understood. Pronunciation means production of utterances of sounds of a language. English pronunciation has various components, such as sounds, stress, and variation in pitch. English learners need to understand the functions of those components as well as the forms. The foreign language teaching always deals with changing of learner’s pronunciation as learners find it difficult to pronounce the English diphthongs. 11 It is very important for second language learners to pronounce the language correctly and follow a particular accent. Kenworthy 1987 states that learner needs to develop concern for pronunciation. They must recognize that poor unintelligible speech will make their attempts at conversing frustration and unpleasant both for themselves and for their listeners. Most English learners do not know how to produce acceptable sounds. They also speak what they hear. Therefore, the English teachers need to concentrate their efforts in teaching acceptable pronunciations to the learners who ultimately might seek admissions in the English speaking countries. Attitude and motivation shall intermittently guide the learners to produce the sounds, which are acceptable to the native learners. That is why English teachers must have the knowledge of phonetics of English and they should know different techniques to teach pronunciation. The main problem of English pronunciation is to build a new set of boxes corresponding to the sound of English, and to break down the arrangement of boxes which is the habits of our nature language have so strongly built up. We do this by establishing new ways of hearing, new ways of using our speech organs, and new ways of habits O’Connor, 1980. 3. Phonetics and Phonology According to Poole, phonology is the study of sounds in the context of language and other varieties of language Poole, 1999. It is the theory about how
