Lupe

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 Speech quality assessment usually depends on subjective judgments after listening to test stimuli. The obtained subjective quality indices are valid and reliable but provide little insight into the underlying perceptual process. Since reverberation is known to influence perceived speech quality and intelligibility, e.g. in conference calls while using a loudspeaker, we analyzed the performance of electroencephalography (EEG), which measures brain activity at the cortical level, for indicating speech stimuli with a high reverberation time as degradation. We collected a database of 22 subjects to test the ability of utilizing EEGdata - especially parameters of event-related-potentials (ERP) - to identify the processing of a stimulus with high reverberation times. The reported preliminary findings provide promising insights: indirect measurements of perceived stimulus quality - without asking for the subjects' opinion - are sensitive to reverberation levels. Correlations between physiological parameters and stimulus features showed that quality degradations can be monitored in conscious stages of stimulus processing. We show that the analysis of ERP is in general a useful and valid tool in quality research. In the case of reverberation, this can actually lead to the indirect measurement of perceived quality with respect to changes of room acoustics.
