This study explores the integration of advanced AI technologies, including emotion detection and adaptive learning systems, to enhance second language acquisition among 274 English as a Foreign Language (EFL) learners. Utilizing a pretest-posttest randomized control trial, the research evaluates the effects of AI-enhanced interventions on emotional self-regulation and linguistic proficiency compared to traditional teaching methods. The results indicate significant improvements in language retention and emotional regulation for learners using AI tools. Qualitative feedback from interviews and surveys corroborates these findings, underscoring the positive impact of AI on educational experiences. This research highlights the potential of AI to deepen emotional engagement and tailor learning experiences, recommending the incorporation of AI technologies into language learning programs to boost linguistic competencies and enrich educational outcomes.
