Computer-assisted language learning (CALL) is reaching an up most position in the pedagogical field of English as a Second or Foreign Language (ESL/EFL). The present study was carried out to study the effect of using phonetic websites on Iranian EFL students’ pronunciation and knowledge of phonemic symbols. Participants of the study included 30 EFL female pre-intermediate students studying in Kish Language School in Tonekabon. A pretest and posttest of phonemic symbols and pronunciation was given before and after the treatment to both experimental and control groups. The results of statistical analysis revealed that the learners’ pronunciation developed better when they took part in web-based training course. On the other hand, the experimental group did not outperform the control group regarding the knowledge of phonemic symbols. This thesis concludes with some implications for teaching and directions for further research.
