| Abstract(in English) | In automatic assessment of pronunciation proficiency for second language learners, phoneme posteriorprobabilities calculated by acoustic model are widely used. In previous studies, assessment is performed usingphoneme posterior probabilities calculated by acoustic model of learning language. However, the learner’s pronunci-ation may be close to the learner’s native language. In this study, we propose a label prediction model by supervisedlearning based on BLSTM using phoneme posterior probabilities calculated by both acoustic models of learninglanguage and learner’s native language. Experimental results showed the effectiveness of using phoneme posteriorprobabilities of language pairs. |
