With the growing maturity of the “technology” + “teaching” integration model, the ethical and legal issues related to AI in English language teaching have become more and more prominent. However, the previous literature has not systematically explored the factors that cause AI ethics and law in English language teaching, nor has it made suggestions to address these factors. Therefore, this paper explores in depth the origins, manifestations, and solutions of these ethical and legal issues. Firstly, through the literature review method, we explore the ethical and legal issues surrounding AI in English language teaching and its impact on teachers and students, and find that these ethical and legal issues have a significant effect on enhancing the legal awareness of students and teachers. Moreover, based on the literature review method, this paper identifies eight influencing factors and determines the weights of each factor through the method of multiple linear regression, and it can be seen that automated decision-making and accountability (X3) and teacher roles and competence (X4) have the greatest weights and are the key factors leading to ethical and legal issues. Finally, this paper also formulates targeted recommendations in response to the experimental results, such as respecting students’ and teachers’ privacy and autonomy, maintaining teachers’ professionalism and accountability, and complying with laws, regulations, and ethical guidelines.
