| Abstract(in English) | We investigate in this paper speech recognition for a person with an articulation disorder resulting from athetoid cerebral palsy. As our previous work, the feature extraction method using a convolutional neural network is proposed, and showed its effectiveness. The neural network needs the teaching signal to train the network using back-propagation, and the previous method uses forced alignment using HMMs from speech data for the teaching signal. However, because the dysarthric speech fluctuates every utterance, it is difficult to obtain the correct alignment. It is considered that the network is not adequately trained due to the wrong alignment. However, phone boundaries for dysarthric speech are ambiguous, and it is difficult to give the correct alignment and it is difficult to give the correct alignment. Therefore, we propose a phone labeling method using the Gaussian distribution. In this paper, we report our experimental results of speech recognition using the networks trained by the phone alignments calculated by our proposed method. |
