It examines the app’s impact on pronunciation improvement, user satisfaction, frequency of use, and the occurrence of technical difficulties. The main objective is to compare the effectiveness of digital language-learning tools, particularly ELSA Speak, with traditional classroom-based pronunciation instruction. Conducted within an educational setting, the research adopts both quantitative and qualitative approaches. Data were gathered from 25 participants between the ages of 13 and 15 through online surveys and questionnaires, using random sampling techniques. The findings reveal that 69.2% of participants considered ELSA Speak more effective than traditional learning methods, while 84.6% reported a highly positive improvement in their English pronunciation. Overall, the results indicate that ELSA Speak is an effective and well-received tool with significant potential for supporting pronunciation development among language learners. The study also highlights opportunities for future improvements and further research to maximize the application’s usability and effectiveness in language education.enhttp://purl.org/coar/access_right/c_abf2ESLA speakpronunciation developmentdigital language acquisitionuser satisfactionlanguage learningThesis
