Abstract

Traditional methods for evaluating degradations in a speech transmission system generally produce a single measure of quality without providing any diagnostic information about the nature of the degradation. In this research, a method is proposed to directly evaluate three orthogonal dimensions: discontinuity, noisiness, and coloration. Naïve listeners are able to distinguish the three dimensions after a brief training phase. The benefit to this approach is a reduced experimental effort that results from a limited number of scales and a reduced number of judgments per stimuli. The method was applied to two listening experiments.
