A dialogue-based CALL system for Japanese conversation

This paper describes a dialogue-based CALL (Computer Assisted Language Learning) system. One of the major problems in CALL systems is that learners are usually assigned a passive role. Learners have no practices in composing their own utterances. The other major problem is that lots of the proposed CALL systems are the pronunciation exercise systems such as minimal pairs. The pronunciation exercise is an unrealistic task, if the goal of the learner is to obtain the ability to participate actively in a conversation. We proposed the dialogue-based CALL system with which learners can practice in making a conversation and in composing utterances actively.
