     View Summary

    © 2016 IEEE.We are working the recognition of inaudible Japanese speech by using surface electromyography. During natural speech, muscle activity changes continuously and gently under the influence of the preceding or succeeding phoneme, even within the utterance of a single vowel. We need to detect the temporal positions of such changes to extract stable features of phonemes. In our previous works, we expected that time position, which is the most distinct feature of a vowel, is the time when the lips are formed clearly. We used CoB, which refers to the center of gravity of wavelet coefficients, to evaluate muscular activity for tracking lips shape. However, the method was complex in terms of execution. It assumes that CoB is a insufficient information for the evaluating muscular activity. CoB is inferior in correlation with muscle strength, because it has frequency features which reflect nervous tissue activity. Therefore, we evaluate muscular activity by using a frequency feature and a signal power feature, and track lip shape. In this paper, we describe a method for tracking lip shape and detecting lip shape peaks, and report the recognition result of the continuous utterance of a pair of inaudible Japanese vowels by using the features around such peaks.
