In recent years, learners worldwide have expressed increasing interest in mobile learning and the utilization of mobile devices for language learning purposes. However, few research synthesis studies have focused on pronunciation development in relation to employing MALL (mobile-assisted language learning). This review article contributes to the discourse on how mobile learning aids in acquiring and practicing EFL (English as a foreign language) pronunciation since it is this language system that is both a crucial and frequently neglected aspect of English language learning. With the emergence of e-generation, it is necessary to investigate the influence of MALL on pronunciation acquisition. This paper provides a systematic literature review of the findings of 15 empirical studies published between 2015 and 2022, which is based on PRISMA 2020. The aim of the review is threefold: to investigate the effect of mobile devices on L2 learners' pronunciation performance, examine learners' attitudes toward employing mobile learning for pronunciation practice and development, and identify which mobile devices and apps are present in the process. The results indicate that overall, mobile learning exerts a beneficial impact on L2 pronunciation and that participants in the reviewed studies demonstrate positive attitudes toward MALL. Moreover, smartphones appear to be at the center of attention as the primary mobile device, and it was revealed that a variety of mobile apps and platforms have been employed in the studies. The article concludes with pedagogical implications and recommendations for potential research exploration in the future.
