Pronunciation is one of the main problems in language teaching and learning and it gets little attention. Most of students underestimate the importance of pronunciation considering that pronunciation is less important than other aspects of language. Many researchers investigated the weakness of pronunciation among students in all stages. However, there is still a strong need to develop pronunciation of foreign language students. This study aims to investigate the effectiveness of using Kahoot application for developing EFL pronunciation and conducted with second year students at advanced level from Translation and Interpretation Department at Selçuk University in Turkey. A diagnostic test provided in a pronunciation course material was used in order to determine mispronouncing sounds. The study followed the two groups (control and experimental) with pre-post-test design. The pre-test was administered to the students of both groups at the beginning. After the administration of the pretest, for instruction session, the control group followed the activities in the course material and experimental group was taught using Kahoot application for the same activities. Then, the post-test was administered to both groups. The results were statistically analyzed (t-test) and the findings revealed that the EFL pronunciation skills of the experimental group were developed as a result of using Kahoot application. It is recommended that Kahoot application can be used in different educational stages for developing EFL pronunciation skills.
