Abstract(in English) | We investigated the performance improvement in automatic evaluation of English pronunciation uttered by Japanese students. The system is based on the error detection method of non-native pronunciation proposed by Kawai et al. in which the acoustic models of two languages are used. In this case, there is a problem of the acoustic mismatch between acoustic models and input speech because of speaker characteristics and/or recording environment. Then we employ the cepstral mean normalization(CMN)or the histogram equalization(HEQ)in order to minimize the acoustic mismatch. In addition, we try to reduce the miss detection of pronunciation error by using the phoneme weighting method while keeping the relative differences between two languages. |
