<![CDATA[The objective of this study was to examine the effectiveness of the ELSA Speak application in enhancing students’ English speaking skills. The research was conducted at SMK Muhammadiyah Pagaralam with a population of 404 students. Two tenth-grade classes were selected, consisting of an experimental group and a control group, each with 33 students. This study applied a quantitative method using a quasi-experimental design, with pre-tests and post-tests as data collection instruments.The results of the paired sample t-test showed that both groups improved after the treatment, but the experimental group improved more significantly. The mean post-test score of the experimental group was 70.73, while the control group scored 65.03, with a mean difference of 5.697. The independent sample t-test indicated that the t-obtained value was 4.217 with a degree of freedom (df) of 64. The t-table value at a 0.05 significance level was 2.000. Since the t-obtained value was higher and the significance level (0.000) was lower than 0.05, the alternative hypothesis (Ha) was accepted. This means there was a significant difference between the two groups, while the null hypothesis (H₀) was rejected. In conclusion, the ELSA Speak application significantly improved the English speaking skills of tenth-grade students at SMK Muhammadiyah Pagaralam.]]>
