This paper examines the improvement of users using BiTak that is assessed objectively by certified language teachers following the scoring tool named Rubric. We created 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 sim-ultaneous bilingual acquisition. We conducted experiments to evaluate the effectiveness of BiTak as well as the improvement of learners through using it and found that the system brings about the sense of language learning and favorably boost students’ speaking skills.
