The subjects for the study were studen ts and teachers at Sudanese universities. The instruments used for collecting the data were a questionnaire, an interview, and group discussion. The researcher found that Sudanese EFL learners have problems when pronouncing English words, especially with: the sounds that are not found in their mother tongue; e.g.: /p/ and /v/ sounds, words that have consonant clusters; e.g.; /school/ and /spent/. Vowels (diphthongs and triphthongs); e.g; the students pronounce /i/ for /e/ as in sit, and overlapping between English and Arabic - students tend to substitute sounds that are not found in their mother tongue, e.g.: they pronounce /b/ instead of /p/ sound as in the word: people.Linguistics
