| Abstract(in English) | As a first step, we consider Japanese lyrics recognition in monophonic singing that contains no musical instruments. To express singing well, we attempt to use an n-gram language model using a lyrics corpus, singing-adapted GMM-HMM-based acoustic models and plural pronunciation lexicons for vowel-lengthening. We attempted to adapt the read-speech AMs to sung-speech AMs using two approaches. One is MAP adaptation and the other is neural network-based feature transformation. For adapting to singing, we use 40 pieces of music sung by 40 male singers. For adapting to speaker, we use a piece of music sung by a male singer who is the same speaker as a singer of a test data. To deal with the property of singing offten involving lengthening the duration of each vowel, we augment the pronunciation variations. Evaluation is performed on a test set that contains 7 pieces of commercial music sung by 7 male singers. As a result of experiments, our system showed syllable accuracy of 46.1% (phoneme accuracy of 59.0%) and word accuracy of 25.9% in male monophonic Japanese singing. This result showed higher accuracy than a conventional system based on the newspaper LM and the read-speech AM. |
