As English continues to be a widely spoken language worldwide, language learners are looking for new and innovative ways to improve their pronunciation skills. This article has reviewed studies on the potential limitations and effective integration of mobile pronunciation tools for English language learners. This review aims to explore and discuss the potential constraints and challenges of using mobile pronunciation tools for English language learning. Additionally, it examined how these tools can be effectively integrated into classroom instruction and self-directed learning. The articles for this review were discovered by using internet search engines such as Google Scholar, Scopus, and Research Gate, in the topic area of the potential limitations and integration of mobile pronunciation tools for English language learners. The retrieved data was carefully investigated using inclusion and exclusion criteria. The topic investigation involved collecting data from ten journals article, which were then analyzed by creating a grid table. The resulting table is used to analyze patterns, similarities, and differences that can help conclude. The results of the analysis show that although mobile pronunciation tools have the potential for helping English language learners improve their pronunciation, they also have some limitations that need to be addressed. For future research, especially for those who are interested in integrating mobile pronunciation tools as the topic of the study, this paper can be a good lesson for the next study.Keywords: Mobile pronunciation tools, English language learners, classroom instruction, self-directed learning
