摘要：

In order to estimate jitter and shimmer, we suggest the method for the detection of precise pitch and amplitude of voiced speech signal. After low-pass filtering, voiced / unvoiced decision and pitch detection is performed using average magnitude difference function (AMDF). We find minimum value at t = tau and also check the possible minimum value at t = tau/2, tau/3, tau/4, tau/5, tau/6. By the application of adaptive threshold, we can estimate pitch more accurately than uniquely applied threshold.
