Conversation courses often need to be taught to large groups of over 40 people because of various management factors of universities. In a large class, the language level of students is not the same and they are motivated differently. Under these circumstances, peer learning seems to be an effective way to manage a class. In this paper I propose voice recording on a smartphone as a tool for conversation training, through which students record their speech, check and correct it with peers. The post-course survey shows that most of students accept this method and see effectiveness in it, however, a few of them are embarrassed to do this activity.
