Abstract(in English) | We investigate speech recognition of a person with articulation disorders by athetoid type of cerebral palsy. Recently, the accuracy of speaker-independent speech recognition has been remarkably improved by use of stochastic modeling of speech. However, the use of those acoustic models causes degradation of speech recognition for a person with different speech style (e.g., articulation disorders). In this paper, 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 propose a robust feature extraction method based on PCA (Principal Component Analysis) instead of MFCC. Its effectiveness is confirmed by word recognition experiments. |
