The Use of AI to Improve English Pronunciation of Adult Learners

Abstract

This research synthesis aimed to examine the effects, benefits, challenges, and students’ and teachers’ perceptions of integrating Artificial Intelligence (AI) tools to improve adult English pronunciation. To achieve this goal, a total of twenty empirical studies were collected and analyzed. All of the articles were written in English and published within the last 10 years. Moreover, they discussed the role of technology in improving pronunciation. The results reveal that applying AI in the learning process to improve pronunciation has a wide range of positive effects as well as a few negative ones. Regarding the most notable effects, there is a noticeable improvement in both segmental and suprasegmental elements, along with a boost in motivation during the learning process. Conversely, just three negative impacts were found. Moreover, several benefits, such as real-time feedback and the availability of the apps, as well as potential challenges, were highlighted. Concerning teachers' and students’ perspectives, positive viewpoints and judgements emerged. Therefore, these apps seem to be a valuable tool for teachers. Lastly, more research needs to be conducted about these tools, considering different aspects, such as underexplored geographic areas, diverse student populations, and language skills.
