| Outline of Final Research Achievements |
The purpose of this research is to recognize natural inaudible speech based on surface EMG signals around lips. During this research period, I studied the recognition method using the center-of-balance transition method on wavelet coefficients of surface EMGs.
A person performs a natural continuous utterance with gentle change of lip shape. Therefore, in order to obtain a good recognition result, it is necessary to identify the proper positions to extract the features for recognition. As such positions, I propose methods to detect the change point of phonemes and the peak point of lip shape change based on center-of-balance transition. However, the first place accuracy rate of the recognition result of continuous vowels is about 60 %. It shows that further improvement is necessary.
