Abstract: Improving English pronunciation is a crucial issue for any learners of English, including Vietnamese students. However, developing students pronunciation, especially non-English majors in a non-native country like Vietnam, faces many difficulties, one of which is insufficient time devoted to in-class pronunciation activities due to the neglect of pronunciation aspects in English teaching and examination systems. The study aims to improve non-English majors’ pronunciation performance in a regional teacher education university in Vietnam through the use of homophone games as well as to assess the impact of homophone games on the pronunciation performance of non-English majors.
