This study sought to investigate the impact of teaching speech acts and role relations through authentic audio-taped and video-taped materials on the level of Iranian EFL learners’ pragmatic competence. To this end, 55 intermediate learners were ed and randomly assigned to two experimental groups: the audio-taped group and the video-taped group. During the treatment, the audio-taped group received instruction through audio-taped materials (various authentic podcasts), while the experimental group through exposure to video-taped materials (extracts some popular TV soap operas). The data analyses conducted prior to and following the treatment in both groups demonstrated that both groups had improved in terms of the knowledge of certain speech acts. However, the video-taped group was shown to have significantly outperformed the audio-taped group.
