In this paper, we investigated the extent to which Computer Assisted Pronunciation Training (CAPT) improved five Iranian English as Foreign Language (EFL) learners’ use of suprasegmental features. The My English Tutor (MyET), computer software, was utilized to train English as Foreign Language (EFL) learners for using suprasegmental features of English pronunciation (e.g., stress, rhythm/timing, and intonation). Data from a two-month direct observation, the second researcher’s and participants’ reflective notes, the feedback and scores provided by MyET, and oral interviews were collected and analyzed. The results revealed that CAPT improved EFL learners’ use of suprasegmental features. Moreover, the oral interview analyses indicated that EFL learners had a positive attitude toward CAPT, which helped them to be autonomous and confident in learning how to pronounce English words and phrases.
