The effectiveness of AI-powered speech recognition tools on improving segmental and suprasegmental pronunciation accuracy among EFL learners
Keywords:
AI-powered pronunciation, EFL, Intelligibility, Learner Autonomy, Intercultural CommunicationAbstract
This study investigates the efficacy of AI-powered pronunciation tools in improving segmental and suprasegmental accuracy among 68 EFL students at Universitas Islam Negeri Fatmawati Soekarno Bengkulu. Utilizing a mixed-methods quasi-experimental design, the study compared an experimental group receiving AI-assisted instruction with a control group using traditional classroom methods over eight weeks. Quantitative results revealed significant proficiency gains in the experimental group ($p < .001, d = 0.95$), while qualitative data indicated that AI tools reduced speaking anxiety and fostered learner autonomy. The findings imply that integrating AI-driven technology into EFL curricula provides a viable pathway to enhance communicative readiness. The study recommends adopting AI-assisted instruction to bridge the gap between classroom practice and real-world intercultural interaction requirements.
