Preface
This book presents the research of the author on the neural correlates of quality perception for complex speech signals. Two different disciplines will be interconnected here, namely neuroscience and Quality of Experience research, which do not seem to be frequently used in combination for research on speech quality perception. In the five experiments conducted here, standard clinical methods in neurophysiology on the one hand, and on the other hand, methods used in fields of research concerned with speech quality perception, will be applied. Using this combination, it will be shown that speech stimuli with different lengths (phonemes, words, sentences and audiobooks) and different quality impairments (signal-correlated noise, reduced bit rate of a speech codec and reverberation) are accompanied by physiological reactions related to quality variations, e.g. a positive peak in an event-related potential. Furthermore, it wil
