Pattern matching unit of our ASI system computed
quantization distortion of X with codebook C of each registered speaker according to Equation (1) as reported by (Quatieri 2002).
Figure 5 shows the
quantization distortion of distributed LBG algorithm (p = 3) and distributed SOM algorithm ([N.sub.t]= 20), as well as the c-LBG, c-SOM, nc-LBG, and nc-SOM algorithms.
The total
quantization distortion D can be expressed in terms of [DELTA], [Q.sub.0], and [Q.sub.1]:
It contains 54 distorted images with six types of distortions including
quantization distortion, noise contamination, and blurring.
