The Extent of AI Applications in EFL Learning and Teaching

Foreign language teaching, like almost all other aspects of human existence, has been substantially influenced by recent advances in modern information and communication technologies, such as augmented reality, virtual reality, and artificial intelligence (AI). Although AI has been in use for almost 30 years, educators remain skeptical toward the use of AI-technology in the education field more broadly, and how its use might meaningfully affect English language skills. Through a systematic review, this work seeks to provide a summary of the available literature with regard to the applications of AI in English as a foreign language (EFL) education. This review considers a wide range of AI technologies and methodologies, with a specific focus on the integration of AI into the realm of EFL education. The review then delineates the possible effects of AI in terms of developing students' language skills, students' and teachers' perceptions of using AI applications, and the difficulties and challenges inherent to implementing AI applications. The discussion culminates by identifying research gaps.
