| Abstract(in English) | A new technique for unvioced speech recognition via EMG signal is presented. Two methods (HMM for EMG-based speech recognition and cepstral coefficient of EMG as feature vector) are described. The HMM which is a useful statistical tool for time serial signal is applied to EMG signal. The LPC analysis is applied for EMG signal and the cepstral coefficient is used as the feature for EMG-based speech recognition. The EMG signals of 10 repetitions of 14 isolated Japanese digits were analyzed. Experimental result showed that HMM was effective in dealing with EMG time serial signal. Another experimental result showed that the mean recognition accuracy of the cepstral coefficient was 9.3% superior to that of using power of EMG signal only as feature. |
