Abstract:
English alveolar sounds. The researchers assumed that Sudanese Arabic speakers substituted some English alveolar sounds; /t, d, s, and z/ with Sudanese emphatic sounds; /t?, d?, s?, and z?/ in some circumstances. The study employed the descriptive analytical method in order to elaborate and analyze the cause of the problem. To obtain the necessary data for the study, the researchers designed a diagnostic test that confined to the study hypotheses via audio-recording. Accordingly after the necessary data were collected then it was analyzed using the means of percentages. Based on the analysis and the results obtained, the study revealed that the Sudanese learners of English as foreign language converted English plain Alveolar sounds; /t, d, s, and z/ with their emphatic sounds /t?, d?, s?, and z?/ whenever preceded or followed by English vowel sounds /ʌ , ɔ:, əʊ, ɑ:, ɒ/.
