Abstract:
Understanding the excitation source of the esophageal speech is a key approach for understanding the esophageal speech. In this paper, we extract the excitation source using an inverse filtering approach and we analyze it. We, for example, show some similarities with an artificial EGG signal. We also detect the closing instants in order to define cycles of opening/closing of esophagus extremity and to recognize the equivalent of glottal cycles. These cycles are classified into different types according to their characteristics. A physical explanation of the esophagus extremity behavior is systematically given at the different steps of the analysis.
