A new speech quality model, DIAL (Diagnostic Instrumental Assessment of Listening), provides diagnostic information in both narrow-band and super wide-band contexts. It is “intrusive,” assuming that the original source audio is available. Because many quality-measuring techniques collapse all degradations into a single score, they do not help developers to diagnose the basis of that score. In contrast, the proposed DIAL model uses four quality dimensions: coloration, continuity, noisiness, and loudness.
