Mispronunciation is still among the frailties of language learners the world over. The present study reports an all-out investigation into pronunciation training for the Persian-speaking EFL learners at the intermediate level of language proficiency. More specifically, the present study investigated (a) the underlying causes of mispronunciation at the level of segmental features, (b) the crucial importance of error analysis prior to developing any materials concerning suprasegmental features, and (c) the effectiveness of materials developed on the basis of the findings in the first two phases of the study. Sixty-Four Persian-speaking intermediate EFL learners were selected as participants for the purposes of this study. Twenty-Four of them assisted in the second and forty of them in the third phase. Since the results obtained in the first two phases were to be used for the preparation of the materials in the final phase, the researchers devised a pretest posttest design to prove or disprove the efficacy of the whole study. Thus, two intermediate classes in one of the language schools in Isfahan were chosen and randomly assigned to experimental and control groups. The first phase of the study confirmed the great impact of Persian language on EFL learners’ English pronunciation (۵۱.۸۲%). The second phase supported the idea that some suprasegmental features such as linking sounds are obstacles to proper pronunciation for Persian-speaking EFL learners. The results obtained from the last phase of the study indicated that pronunciation training with supplementary materials is rewarding albeit the progress might be slow.
