This study investigated the effectiveness of the ELSA Speak application in
enhancing students’ pronunciation ability at SMK Yadika Palu. Pronunciation is
an essential component of speaking skill, yet many EFL students experience
difficulties in producing accurate phonemes and applying correct word stress due
to limited practice, low confidence, and lack of motivation. This research
employed a quantitative method with a quasi-experimental design involving an
experimental group and a control group, with a total of 40 eleventh-grade
students divided equally into two classes. The experimental group received
pronunciation practice using the ELSA Speak application, while the control
group was taught through conventional methods. Data were collected through
pre-test and post-test assessments focusing on phoneme articulation and word
stress, and analyzed using descriptive statistics, the Shapiro–Wilk normality test,
the Mann–Whitney U test, and effect size calculation. The findings showed that
both groups had similar pre-test mean scores, indicating comparable initial
pronunciation ability; however, after the treatment, the experimental group
achieved a significantly higher post-test mean score than the control group. The Mann–Whitney U test confirmed a statistically significant difference (p < 0.05)
with a very large effect size, indicating that ELSA Speak had a strong impact on
improving students’ pronunciation performance. In addition, students
demonstrated increased motivation and confidence during the learning process,
suggesting that ELSA Speak is an effective Mobile-Assisted Language Learning
(MALL) tool to support pronunciation instruction in vocational high school
contexts.
