This case study aims at answering the two main research questions: (a) What are students’ experiences with and attitudes towards the implementation of audio-visual recording in English pronunciation classrooms? and (b) How does this technique impact their English pronunciation? In order to address these two research questions, both quantitative and qualitative data were collected after the implementation of the technique from 80 freshmen of a state university in the South of Vietnam. Descriptive analysis along with thematic content analysis of the collected data were categorized into three critical areas consisting of students’ experiences with the technique, their attitudes towards the technique, and impacts of the technique. The findings showed that students had very positive attitudes towards this implementation. Particularly, this technique has helped the students improve their pronunciation within the parameter of intelligibility. Based on the research results, possible implications have been discussed for instructing phonetics and phonology as well as for further studies on the important topic of how to enhance students’ pronunciation in the EFL context.
