Use of harmonic phase information for polarity detection in speech signals

Phase information resultant from the harmonic analysis of the speech can be very successfully used to determine the polarity of a voiced speech segment. In this paper we present two algorithms which calculate the signal polarity from this information. One is based on the effect of the glottal signal on the phase of the first harmonics and the other on the relative phase shifts between the harmonics. The detection rates of these two algorithms are compared against others established algorithms.
