Abstract We present an analysis of technical causes and corresponding perceptual dimensions of the quality of transmitted speech. Four experts annotated speech files of a common database according to a methodology which is currently being discussed for the future ITU-T Recommendation P.TCA. The annotations are analyzed with respect to their frequency and consistency, and compared to overall quality values as well as perceptual dimension scores, obtained either from subjective experiments or from instrumental models. This way, links can be drawn between technical causes and perceptual dimensions in diagnostic quality assessment of transmitted speech, and the proposed procedures of several upcoming ITU-T Recommendations can be initially validated.
