Speech signals with sample patches. The bottom plot shows the NSIM similarity score for each patch from the reference compared frame by frame across the degraded signal. The NSIM score is the mean of the individual patch scores given in parenthesis. (a) Time offset between reference and test signal. (b) Patch tested per frame. (c) Maximum NSIM for matching patches for Patch # 1.
