Beschreibung
Zusammenfassung:	In the pitch searching method of the voice signal at the voice signal coding process by the vocoder, the method comprises the steps of: detecting the positive interval of the correlation which is high self-correlation among pitch relay values of the mixed signal from the remained signal of the voice signal, selecting the pitch searching interval, and excluding a negative interval of the remained correlation from the pitch searching interval by using symmetrical characteristics of the self correlation.
