چکیده (انگلیسی):

This study attempts to measure the influence of a language course on the elimination of pronunciation
problems of English vowels that are experienced by Saudi students as a result of a complex letter-sound
relationship. The course was intended to boost the students' awareness of the letter-sound relation ofEnglish
vowels. The course comprised language items such the nature, classification and letter-sound relationship of
vowels reinforced by practice activities. Test material comprised three lists of English monosyllabic,disyllabic
and multi syllabic words that were arranged into pre-and–post tests for comparison purpose. The
participants of the study included the students of English, at Al Baha University who do not have any kind
of exposure to native English. In the tests, students were asked to pronounce words making advantage of
deciphering and pronunciation abilities they developed after the course. Results revealed that the
pronunciation of English vowels of Saudi students improved with respect to English vowel on monosyllabic
and disyllabic words probably due to the language course. However, they have difficulty pronouncing
deciphering vowel sounds in multi syllabic words. Although the course delivered is crucial for the
improvement of learners' vowels pronunciation, listening practice will probably form a robust strategy in
accomplishing the learners' awareness of pronunciation.
