Description
This study investigates the effectiveness of Duo Lingo, a mobile-assisted language learning (MALL) tool, in improving the pronunciation skills of first-year university non-English major students. With pronunciation often neglected in traditional English language curricula, particularly for non-English majors in Vietnam, this research explores how Duo Lingo’s features can address these gaps. Employing a mixed-methods approach, the study combines quantitative data from pre- and post-tests with qualitative insights from questionnaires and semi-structured interviews. A total of 30 students participated in an 8-week intervention, engaging in daily Duo Lingo sessions of 10-15 minutes. Quantitative results revealed statistically significant improvements in segmental pronunciation features as well as marginal gains in suprasegmental aspects. Qualitative findings highlighted positive user experiences with the app’s accessibility, engaging gamification, and native speaker models. Participants reported increased confidence in their oral proficiency; however, limitations in Duo Lingo’s pronunciation feedback and its limited focus on connected speech and rhythm were frequently cited. The study concludes that Duo Lingo is an effective supplementary tool for foundational pronunciation improvement, especially for segmental features. Yet, its integration into university-level instruction requires complementary methods addressing suprasegmental pronunciation and communicative fluency. Pedagogical implications include leveraging Duo Lingo as a cost-effective, scalable option for autonomous learning while supplementing it with classroom-based pronunciation activities for holistic skill development. This research contributes to the growing body of literature on MALL in non-English major contexts, offering practical insights for educators and policymakers in language education.
