This study attempts to explore the utilization of LINE video call for teaching pronunciation using the TikTok video, seen from teacher and students' perspectives. This qualitative study involves a teacher and three students in Thailand interviewed through an online platform. The findings showed that both teacher and students gained a positive attitude towards utilizing LINE video call for teaching pronunciation using TikTok. The benefits are increasing students' vocabulary, building self-confidence in pronouncing the words in English, and more interest in joining the class since the application is not boring. On the other hand, the teacher has a problem with the limited time in creating the materials and making the students focus on the learning process. Yet, the students have a problem with internet connection and many assignments to do during online learning. Finally, the students are enthusiastic since TikTok and LINE video calls help them learn English, especially their pronunciation.
