We investigated the speech recognition of a person with articulation disorders resulting from athetoid cerebral palsy. The articulation of the first words spoken tends to be unstable due to the strain placed on the speech-related muscles, and this causes degradation of speech recognition. Therefore, we proposed a robust feature extraction method based on PCA (Principal Component Analysis) instead of MFCC, where the main stable utterance element is projected onto low-order features and… CONTINUE READING
