abstract = {For diagnosing quality degradations in speech transmission and communication
services, auditory degradation decompositions by quantifying perceptual quality
dimensions have been established. However, it is still unclear which technical
characteristics of the underlying systems are the root causes for each perceptual degradation.
In order to investigate the relationship between perceptual quality dimensions
and technical root causes, 8 databases of super-wideband transmitted speech
samples judged regarding 3 or 4 perceptual quality dimensions have been analyzed.
The results show that each perceptual dimension is triggered by a variety of (plausible)
root causes. In turn, several root causes trigger more than one perceptual quality
dimension. Implications of these findings for instrumentally estimating perceptual
quality dimensions are discussed.},
