Jan-Niklas Voigt-Antons joined the Telekom Innovation Laboratories as a research scientist in January 2009 and is working there since 2014 as a senior research scientist. He received his diploma in psychology in 2008 from the Technische Universität Darmstadt, Germany, a Doctor-of-Engineering degree in 2014 from the Technische Universität Berlin, Germany and has been doing research at the Quality and Usability Lab at the Technische Universität (TU) Berlin, since. His research interests are in Quality-of-Experience evaluation and its physiological correlates with an emphasis on media transmissions and human-machine-interaction, including neural processing of multimodal interaction. During summer 2012 he was visiting researcher at MuSAE Lab (INRS-EMT), Canada where he examined neural correlates of quality perception for complex speech signals. In spring 2014 he was visiting researcher at the department of psychology of NTNU, Norway where he examined neural correlates of audiovisual asynchrony.

Zusammenfassung In telecommunication research, subjective listening tests are commonly used to measure the perceived quality of speech stimuli. Disadvantageously, these approaches do not provide information about possible subconscious processes which could prime for slowly growing dissatisfaction with an audio transmission. Here, we propose to analyse brain EEG activations related to stimulus quality. This objective information could be informative particularly for minor degradations of auditory hi-fi stimuli where reports of quality differences are notoriously subjective and variable. Accordingly, we ran an EEG study (N=11) using an auditory oddball paradigm: subjects pressed a button whenever they detected a noise disturbance in a set of naturally spoken vowel /a/ stimuli which either were left unmodified (non-targets) or were modified by adding signal-correlated noise at four intensity levels (targets). Most remarkably, in five subjects we found a striking similarity in the averaged EEG patterns elicited by marginally noisy stimuli (mean noise perception rate 43%) which were either missed (no button press) or consciously recognized (button press). Consequently, we trained a classifier based on shrinkage LDA to distinguish between single-trial EEG patterns of hits (detected targets) and nontargets for a given subject. Notably, these classifiers were found capable to distinguish also between misses and non-targets in the same subject - two events which are seemingly similar at the behavioral level (i.e., no button press). Thus, EEG-based classifiers are able to identify instances where an audio stimulus is labeled 'hi-fi' consciously - neurally, however, its actual noise contamination is nonetheless detected, possibly affecting the long-term contentment with the transmission quality.
