Abstract

In this chapter, the first and second contributions of this book will be introduced. First, a test set-up combining neurophysiological and subjective quality assessment methods for speech quality perception testing will be presented. Secondly, the functionality of this set-up will be validated for short speech stimuli with the length of phonemes and a generic quality impairment, i.e. signal-correlated noise. It will be shown that a test set-up combining neurophysiological and subjective quality assessment methods for speech quality perception testing is suitable for measuring the perceived speech quality, and in some instances (trials) it is advanced in comparison to a standard subjective test set-up.
