This study aims to determine the effectiveness of the Praktika.AI application in improving the speaking ability of eleventh-grade students at SMKN 3 Parepare. This research employed a quasi-experimental design involving pre-tests and post-tests. The participants were eleventh-grade students from two classes: XI Fashion as the experimental group and XI Computer Network and Engineering as the control group. The instrument used in this study was a speaking test assessed based on three aspects: fluency, vocabulary, and pronunciation. Data analysis was carried out using SPSS. The results showed a significant difference in speaking ability between students taught using Praktika.AI and those taught using conventional methods. The post-test comparison showed that the experimental class outperformed the control class in fluency, vocabulary, pronunciation, and overall speaking score. Based on the calculation of the average questionnaire score in the experimental class, the score was 87.59%, which indicates that respondents' perceptions of the treatment or learning media were in the very good category. Therefore, the implementation of Praktika.AI proved to be able to improve the speaking ability of eleventh-grade students at SMKN 3 Parepare.
