The progress of Automatic Speech Recognition (ASR) has pushed forward research on Computer Aided Language Learning (CALL) systems which recognize speech constructed by students on their own. Reliable recognition is still difficult for spontaneous speech by the second language speakers. We are developing a dialogue-based CALL system which
shows answers in Japanese to achieve high recognition accuracy. In this paper we propose a novel classification method which classifies the speech recognition result from the recognizer using the FSA into accepted or rejected. The classification method adopts differences among acoustic likelihoods from the multiple recognizers as well as edit distances among the multiple recognizers’ outputs as features for the classifier. |
