Description
In this paper, we propose a video chat system named BiTak which employs strict turn-taking dual-lingual communication using recording function. BiTak aims to motivate the dual-lingual conversation between Japanese and International students as well as to identify the mutual benefits through this kind of conversation for the need of improving simultaneous bilingual acquisition. The two most outstanding features of BiTak is following two functions: 1) a strict turn-taking function by discretely recording each utterance and 2) a text chat function related to each recorded utterance. We conducted experiments to evaluate the effectiveness of BiTak and found that dual-lingual communication brings about the sense of language learning while strict turn-taking function favorably and recording function boost students' speaking skills. It is recommended to integrate all of three characteristics for achieving best results in practicing second language speaking skill.
