DEVELOPING PRONUNCIATION SKILLS FOR HIGH SCHOOL STUDENTS THROUGH THE DUOLINGO APPLICATION

English has grown in popularity and is now taught in many schools and used in everyday life in many nations. It has received attention and is now considered a fundamental ability for all students. Additionally, there has been a growing emphasis on helping pupils improve their pronunciation. The efficacy of the Duolingo in helping high school students improve their pronunciation was examined in the research that followed. Based on a 7-week experimental process at a high school, 50 students participated simultaneously. They were divided into two groups. With the control group, they studied according to the traditional teaching method at school. Meanwhile, the remaining 25 students in the experimental group used the Duolingo app to support their pronunciation skills. Data collection methods included pre-test and post-test to evaluate the results before and after the experiment. A questionnaire was designed to survey the difficulties that students encountered in the process of learning phonetic skills. A series of findings and monitoring have shown that the Duolingo is really effective and has a positive impact on students. This study indicated the Duolingo's benefits and its potential for development when integrated into general education programs and education as a whole. At the same time, the study shows that Duolingo has made important contributions to becoming a creative tool that is accessible to various disciplines, as well as innovating and fostering effective and exciting learning experiences.
