A multi-dimensional approach to predicting speech quality using a physiologically motivated model of the Cochlea

This paper introduces a framework to measure speech quality in a multi-dimensional space. A hydro-mechanical Cochlear model is used to convert speech into the perceptual domain, where salient features are extracted to detect temporal and frequency localized distortions. Overall quality evaluation is subsequently achieved using a weighted sum of the detectability of individual distortions.
