This study investigated the effects of video dubbing on EFL learners' pronunciation as well as explored their attitudes toward the technique at a private school in the Mekong Delta. A quasi-experimental design that followed a pretest-posttest group gathered both qualitative and quantitative data to address these issues. The participants are young EFL learners with A2-level English proficiency. The quantitative data was collected and analyzed through pre- and post-tests to measure the effects of video dubbing on young EFL learners' pronunciation before and after the treatment. Meanwhile, a questionnaire and semi-structured interviews were used to collect quantitative and qualitative data on participants' attitudes toward the impact of video dubbing. The findings showed significant improvement in participants' consonants, vowels, stress, intonation, and overall pronunciation. Besides, the learners expressed positive attitudes toward the technique, pointed out difficulties, and gave relevant suggestions. The implications and limitations of the study are also discussed.
