Abstract
Voice production is a complex process involving precise control of a series of events in the peripheral phonatory organs by the central nervous system.
Fluctuations have been observed in normal voice production which increase to a considerable extent in pathological voices. These fluctuations in voice are
termed as pitch and amplitude perturbations or jitter and shimmer respectively which have attracted the attention of several researchers.
