TWISTING TONGUES: ENHANCING GRADE 9 ENGLISH PRONUNCIATION THROUGH PHONETIC TONGUE TWISTERS INCORPORATING ELSA SPEAK

This study investigated the impact of using phonetic tongue twisters combined with the ELSA Speak app on improving English pronunciation among Grade 9 learners in Integrated Schools in the Philippines. Employing a mixed-methods approach, the research measured the significant difference between pre-test and post-test pronunciation scores and explored students’ experiences through interviews. Descriptive statistics showed that students’ mean pronunciation scores increased from pre-test (M = 5.10, SD = 8.63) to post-test (M = 10.87), indicating a notable improvement after the intervention. Inferential analysis using a paired samples t-test revealed a statistically significant difference between the pre-test and post-test scores, t(30) = 16.00, p < .001. The calculated Cohen’s d = 2.00 indicated a very large effect size, suggesting that the intervention had a substantial impact on students’ pronunciation proficiency. Thematic analysis of interview responses revealed positive student attitudes, increased motivation, and enhanced confidence in speaking English. These findings suggest that integrating technology-assisted pronunciation practice with traditional phonetic exercises effectively supports English language learning in secondary education.
