English pronunciation training for real-world communication tasks is crucial in EFL learning because it is essential to learners' listening comprehension and speaking competence. As the e-generation emerges, computer-assisted pronunciation training (CAPT) has begun to receive more recognition in academic institutions for pronunciation learning. Despite its prevalence, dubiety still remains in regard to its effectiveness in pronunciation and learners' perception. This paradox has motivated researchers and language instructors to probe other means of effective pronunciation instruction. In the present study, the researcher aims to explore the effects of mobile-assisted pronunciation training (MAPT) on L2 learners' pronunciation performance. The results revealed that MAPT learners not only held a more positive attitude toward the training course and the mobile application but also made significant improvements in pronunciation. Moreover, there was a non-significant interaction between learners' English proficiency level and teaching methods.
