Dr.-Ing. Jan-Niklas Voigt-Antons


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.

Abstract The assessment of perceived quality and experienced affect of users towards different audio and speech quality levels using subjective rating methods is a common and valid approach. In case that researchers are interested in the subjective a) quality and b) affective rating, participants have to rate the stimuli on both scales. Even though subject should just rate only one of the scales to be not influenced by the questions asked in the other questionnaire, researchers in practice frequently present various scales in a sequence to subjects. This paper examines the effect of questionnaire order on perceived quality and experienced affect by comparing the ratings of two groups of subjects which filled in questionnaires in different orders after listening to the same set of stimuli. We showed that the order of sequence had a significant effect on perceived quality and experienced affect as e.g. the quality of stimuli was rated lower if the quality rating not occurred instantly after stimulus presentation. Thus we want to create awareness for these effects and presented first guidelines to overcome them.
