The participants were 35 third-grade (class 12) students from the Office Automation &amp; Governance (Airport) department. The researchers adopted a quantitative case study approach and selected the participants using purposive sampling. Analysis of the pre-test and post-test results revealed that the ELSA Speak application contributed positively to students’ pronunciation skills. The average post-test score (83.49) exceeded the average pre-test score (77.20), suggesting improvement. The normalized gain (N-gain) score, used to assess the enhancement of scientific process skills and cognitive learning outcomes before and after the intervention, was found to be 5.5.
