Dimension-based Diagnostic Prediction of Speech Quality
Sebastian Möller, Ulrich Heute · 2012
In this paper, we address models for predicting the quality of speech transmission and communication services. In contrast to models which aim at predicting the integral quality of speech, i.e., at an index for the overall quality, we focus on models which predict individual dimensions of quality, as they are subjectively perceived by a communication partner. Such predictions of individual dimensions can then be combined to form an integralquality estimation; however, they may also be used separately in order to diagnose the reasons of insufficient quality. Beyond, describing particular perceptual effects rather than technical systems, they are less vulnerable by new system variants not included in the model development.
