In this work several approaches of amplitude contours estimation for shimmer measurement are analyzed and compared. The approaches covered incorporate a waveform matching procedure proposed in this work, based on existent least squares measures. The experimental comparisons evaluate each method's sensitivity to periodicity perturbations like jitter, shimmer, and noise, as well as their combination. The waveform matching technique shows a better overall performance than the other methods.
