The characteristics and effects of peer feedback on second language pronunciation

Abstract

Abstract In order to investigate the characteristics and effects of peer feedback targeting second language (L2) pronunciation, the present study recruited 32 Mandarin-speaking learners of English who received five pronunciation instructional sessions through an instant messaging application on their smart phones. The phonological targets, types, and formats of peer feedback as well as its effects on their pronunciation (i.e., comprehensibility and accentedness) were examined. Results revealed that the participants mainly targeted segmental errors rather than suprasegmental errors and that they tended to provide more feedback on vowels rather than on consonants. Their feedback, delivered mainly in writing, was found to be effective in improving learners’ comprehensibility, but not their accentedness. The findings demonstrate the potential of peer feedback complementary to teacher feedback in instructed L2 pronunciation and highlight the importance of training in optimizing the effectiveness of peer feedback.
