Abstract(in English) | Recently, the accuracy of speaker-independent speech recognition has been remarkably improved by use of stochastic modeling of speech. However, there has been very little research on orally-challenged people, such as those with speech impediments. Therefore we have tried to build the acoustic model for a person with articulation disorders. The articulation of the first utterance tends to become unstable due to strain of a muscle and that causes degradation of speech recognition, where MFCC (Mel Frequency Cepstral Coefficients) is used as speech features. Therefore we proposed a robust feature extraction method based on PCA (Principal Component Analysis) instead of MFCC. In this paper, we discuss our effort to integrate a Metamodel and Acoustic model approach. Metamodel has a technique for incorporating a model of a speaker's confusion matrix into the ASR process in such a way as to increase recognition accuracy. Its effectiveness is confirmed by word recognition experiments. |
