This paper reports on a study that attempted to examine the effect of explicit pronunciation instruction of some English segments (individual sounds) on the degree of perceived foreign accent in EFL Arab learners’ speech. Nine Arab learners of English in an EFL (English as a foreign language) setting were assigned to two groups, experimental and control. Five utterances loaded with the taught segments were collected from both groups before and after instruction. While the experimental group received instruction on these segments, the control group did not. 13 native English listeners were recruited to rate all the elicited sentences for the degree of perceived foreign accent. The results did not show any effect of explicit pronunciation instruction on the degree of perceived foreign accent, as there were no differences between the ratings before and after the instruction.
