Effects of Video-based Shadowing on Suprasegmental Features: EFL Learners' Pronunciation Performance and Attitudes

The study was conducted to investigate the effects of video-based shadowing on pre-intermediate EFL learners' pronunciation performance of suprasegmental features as well as explore their attitudes toward the technique. The study employed three instruments including pre-and post-tests, a questionnaire, and semi-structured interviews, to triangulate the data. The results showed that participants made an improvement in their pronunciation performance of suprasegmental features, especially intonation. In other words, video-based shadowing has positive effects on the participants' pronunciation performance of suprasegmental features. Besides, they had positive attitudes toward video-based shadowing and outlined some benefits of using the technique. Furthermore, the participants' preference for how to practice video-based shadowing was also discovered.
