The role of changes in pronunciation ability and anxiety through Gen-AI on EFL learners’ self-directed speaking motivation and social interaction confidence - A CHAT perspective

Texto completo

This study examines the impact of Gen-AI on EFL learners' foreign language (FL) pronunciation ability, FL speaking anxiety, self-directed speaking motivation, and social interaction confidence through Cultural-Historical Activity Theory (CHAT). Using a mixed-methods approach, the study conducted quantitative assessments of pronunciation ability and speaking anxiety, while qualitatively exploring learners' experiences with Gen-AI feedback through in-depth interviews. Findings suggest that learners experienced improvements in pronunciation ability and reductions in FL speaking anxiety, which coincided with increased self-directed motivation and social interaction confidence. When combined with emotional support from teachers and peers, Gen-AI use appeared to foster both technical development and affective growth.
