Abstract

This study investigated the effects of AI chatbot interaction on EFL learners’ foreign language speaking anxiety (FLSA), willingness to communicate (WTC), and speaking proficiency. Forty-eight Korean EFL learners were assigned to either an experimental (n = 24) or a comparison group (n = 24). The experimental group engaged in conversations to complete speaking tasks using the mobile-based app ChatGPT-4o, while the comparison group conducted face-to-face conversations with peers. Data collection included pre- and post-task assessments and questionnaires measuring FLSA and WTC. Speaking proficiency was evaluated across five dimensions: grammar, vocabulary, fluency, pronunciation, and task fulfillment. The findings indicated that the use of an AI chatbot during speaking tasks was significantly more effective than peer interaction in reducing FLSA and enhancing WTC and speaking proficiency. Notably, participants who interacted with ChatGPT showed significant gains in grammar, vocabulary, and task fulfillment, while no significant differences were found between groups for fluency and pronunciation. These results highlight the potential of integrating AI chatbots into EFL speaking instruction to help learners overcome affective barriers and enhance oral proficiency.
