Language Interference in Teaching English Diphthongs to Uzbek Learners

The interference of vowels in teaching English has been studied on the examples of languages such as Urdu, Russian, and Sundan, in which the causes of the interference of vowels have been revealed. This research is devoted to the problem of linguistic interference in the process of teaching the pronunciation of English diphthongs and their written expressions to Uzbek native speakers. The aim of the study is to identify the interference of diphthongs caused by the interaction of the Uzbek and English languages and develop a method to eliminate them. The comparative-contrastive method has been used to determine the interference of diphthongs. The research distinguishes two types of linguistic interference associated with teaching diphthongs. They are the phonetic-phonological and orthographic interference of diphthongs.  The reasons for appearing of these types of interference are explained by convincing examples.  The research proposes a new method to eliminate the phonetic-phonological and orthographic interference of diphthongs in teaching English to Uzbek native speakers.  This method is called Vowel Spelling and Pronunciation. The application of new method and its advantages are explained in detail. The research is concluded that the use of the Vowel Spelling and Pronunciation method is fruitful in the effective teaching of English diphthongs to the Uzbek audience.
