概要	This study implemented an English as an International Language (EIL) learning program using AI-synthesized non-native English voices with 15 Japanese university students across five sessions. To examine its effectiveness, pre- and post-questionnaires and open-ended reflections were analyzed. Although no statistically significant improvement was observed in listening test scores, a positive trend emerged in the Strategies for Multilingual/Multicultural Communication subscale. Furthermore, the findings indicated that learners developed more receptive and appreciative attitudes toward diverse English accents.
