THE IMPACT OF MICROSOFT IMMERSIVE READER ON THE PRONUNCIATION ACCURACY OF EFL LEARNERS

The study aims to examine how Immersive Reader (IR), an online tool, affects the pronunciation accuracy of English as a Foreign Language (EFL) learners using a quasi-experimental study. The study involved 230 EFL learners aged 15 to 22 at an intermediate level in a private institute in Vietnam. Participants were grouped into 2. One group was asked to use IR for practicing pronunciation; the other applied the traditional method with textbook audio for 3 weeks. Pronunciation was then evaluated through pre- and post-intervention assessments regarding individual speech sounds (segmental), prosodic features (suprasegmental), and fluency. The experimental group's results show considerable gains, implying that IR effectively improves EFL pronunciation.
