Abstract

The purpose of this study is to highlights innovative applications of artificial intelligence (AI) in enhancing English language proficiency among Japanese learners. The first study investigated how non-English major university students improved speaking skills through smartphone recordings, AI analysis using ChatGPT, and peer assessment over ten weeks. Results revealed enhanced fluency and motivation, with AI feedback and collaborative evaluations fostering critical self-reflection and autonomy. The second study examined Transable (Tr), an AI tool for technical college students, which evaluated and revised essays according to CEFR standards. Tr notably increased unique vocabulary usage, improved fluency, and raised CEFR scores by offering detailed, objective feedback and targeted corrections, supporting independent learning and writing habit development. The third presentation explored AI-based tools Scribo (writing) and Progos (speaking) at Japanese universities, demonstrating that AI facilitates timely feedback, boosts motivation, and allows educators to focus on advanced skills, while human oversight ensures fairness. Overall, the symposium advocates for a blended approach, combining AI’s efficiency with human expertise, to optimize language learning in the digital era.
