Spectral Distortion Measures for Speech Compression.
Abstract
In recent years several measures of distortion between speech waveforms have been proposed as substitutes for the traditional but subjectively inadequate mean-squared error. All of these measures involve some form of distortion measure between the second order properties of the speech processes producing the waveforms instead of an average of the waveform error power. In particular, they depend on the power spectral densities or linear models of the speech process. In this report the properties and interrelations of several such measures are developed. In particular, the relative strengths or equivalences of the various implications and applications of these measures to prediction, detection, and coding are summarized. (Author)
