Speaker
Description
This study evaluates how an interactive artificial intelligence voicechat training model affects the performance of thirty-two engineering students at Hanoi University of Science and Technology on the TOEIC Speaking test. Selected through purposive sampling due to their low-to-intermediate initial language levels, the participants followed an iterative practice-and-correction self-studying cycle to complete TOEIC-speaking-test tasks, including responding to questions and expressing opinions. Data analysis comparing two consecutive speaking attempts showed that the chatbot helped students improve the way they organize and structure their spoken responses. Over half of the participants immediately built better structured responses on their second attempt by using time-management patterns and transition phrases, whereas their overall grammar accuracy and pronunciation remained unchanged. This reveals that the participants’ response templates were more instant to automated feedback of the chatbot, but it is more difficult to quickly enhance their speaking habits and regular mistakes. The research indicates that artificial intelligence voicechat should not completely replace the teacher but used as an automated tool to provide immediate diagnostic feedback. These findings suggest that future TOEIC Speaking preparation courses should assign repetitive question practice to artificial intelligence platforms. Thus, during classroom hours, human teachers can focus on specific language problems facing engineering students most.
