| Abstract(in English) | While high recognition performance has been achieved for read speech, rather poor performance has been reported for spontaneous speech recognition because it has various problems, such as hesitations, filled pauses, unclear pronunciation, and so on. In particular, acoustic variation caused by coarticulation has become a serious problem. In order to solve the problem, context-dependent models such as triphone or quinphone are used for recognition. However, the strength of coarticulatory effect varies widely in spontaneous speech. In this study, we attempt to improve the recognition performance by using a technique of word graph combination in which various acoustic models are combined. |
