Biography:
  Sebastian Arndt is a researcher at the Quality and Usability Lab of the Telekom Innovation Laboratories, TU Berlin. He studied Computer Science at Technische Universität Berlin and received his diploma in 2010. He received his doctoral degree (Dr.-Ing.) in 2015 with the thesis title 'Neural Correlates of Quality During Perception of Audiovisual Stimuli'. His current research focus is on physiological changes during the perception of audiovisual quality. 2012 he was a visiting researcher at MuSAE Lab (Montreal, Canada) in order to work on multimodal neural correlates for synthesized speech.

Zusammenfassung The tolerance limit for acceptable multimediaquality is changing as more and more high quality servicesapproach the market. Thus, negative emotional reactions toward slow quality services may cause user disappointment and are likely to increase churn rate. The current study analyzeshow different levels of synthetic speech quality, obtained from different text-to-speech (TTS) systems, affect the emotional response of a user. This is achieved using two methods: subjective, by means of user reports; and neurophysiological by means of electroencephalography (EEG) analysis. More specifically, we analyzed the frontal alpha band power and correlated this with the subjective ratings based on the Self-Assessment Manikin scale. We found an increase in neuronal activity in the left frontal area with decreasing quality and argue that this is due to user disappointment with low quality TTS systems as they become harder to understand.
