| Research Abstract |
Efficiency on utterance learning of 2nd language is degraded when multiple learners exist in CALL room due to the simultaneous utterances by other learners. A purpose of the research is to improve the performance on utterance evaluation when the simultaneous utterances exist for sustainable learning. The system enhances a target learner's utterance using signals of other learner's utterances and multi channel synchronization technique based on network time protocol.
