Method and apparatus for indicating the emotional state of a person

摘要

A method and apparatus for indicating the emotional state of a person by the person's speech, by: detecting speech waves of the person (SD); subjecting the detected speech waves to a backward and forward inverse filtering operation to obtain residual signals (1); cross-correlating the residual signals to produce a cross-correlated output (3); integrating with maximum overlapping the backward and forward residual signal (3), thereby achieving an estimation of the glottal wave; and processing the above glottal wave estimation to provide an indication of the emotional state of the speaker (4).
