| Abstract(in English) | In recent years, context-dependent subword units have been often employed for large-vocabulary speech recognition systems using HMMs. Since the amount of training data available is usually not large enough to estimate the parameters of all the units with sufficient accuracy, most of these systems use clustering methods to reduce the degree of freedom. However, none of these clustering methods have given a stop criterion of the clustering. In this paper, we propose one clustering method which use MDL criterion as the stop criterion. The cvaluation experiment proved that the proposed method achieved as high recognition accuracy as conventional heuristic methods with less computational amount. |
