Source-system windowing for speech analysis

In this paper we propose a speech-analysis method to bring out characteristics of the vocal tract system in short segments which are much less than a pitch period. The method performs windowing in the source and system components of the speech signal and recombines them to obtain a signal reflecting the characteristics of the system in the chosen window. This method of speech analysis clearly brings out the differences in the vocal-tract system characteristics in the closed and open glottis regions within each pitch period
