Abstract:
Speaking proficiency is a crucial skill for global communication, yet many Thai secondary school students
struggle with fluency and confidence due to limited exposure to authentic language use and traditional
grammar-focused instruction. Existing research on AI-assisted language learning highlights its potential, but
studies on AI Gliglish in Thai classrooms remain scarce. AI Gliglish is an AI-powered English learning platform
designed to provide real-time speech assessment, feedback, and interactive conversation practice. This study
investigates the effectiveness of AI Gliglish in enhancing students’ speaking proficiency and confidence using a
Classroom Action Research approach. Data were collected from 30 Grade 7 students at Muslim Satun Wittaya
School, Thailand, through pre-test, post-test, interviews, and classroom observations. Findings indicate a 19.25%
improvement in speaking scores, increased student participation, and reduced speaking anxiety. The Paired
Sample T-Test (Sig. 0.001 < 0.05) confirms a statistically significant impact. These results suggest that AI Gliglish
effectively enhances speaking skills, supporting its integration into English language education to foster
engagement, fluency, and confidence.
