Objective and subjective assessment of bandlimited signaling speech quality
Main Article Content
Abstract
The coefficients of correlation and matching maps of the results of objective and subjective assess-ment of the speech quality for signals distorted due to the bandwidth limitations had been evaluated. It is shown that matching maps are much more useful in comparison with correlation coefficients because, firstly, they perform the function of the calibration factor and, secondly, they allow the possibility of non-linear dependence between objective and subjective speech quality assessments.
