Voice samples were elicited following game events that were either conducive or obstructive to the goal of winning and were accompanied by either pleasant or unpleasant sounds. Acoustic analysis of the speech recordings of 30 adolescents revealed that mean energy, fundamental-frequency level, utterance duration, and the proportion of an utterance that was voiced varied with goal conduciveness; spectral energy distribution depended on manipulations of pleasantness; and pitch dynamics depended on the interaction of pleasantness and goal conduciveness. The results suggest that a single arousal dimension does not adequately characterize a number of emotion-related vocal changes, lending weight to multidimensional theories of emotional response patterning Affective speech Computer game Elicited Dewey 128.37 15 Centre interfacultaire en sciences affectives 0D8 false 1241 Affective sciences Emotion 5 4 106711c6-6586-4bfb-8e58-7d7fa4ca5a78 Article (Published version) Restricted AffectiveSpeechElicited2005.pdf 89987 application/pdf restrictedAccess Centres et instituts / Centre interfacultaire en sciences affectives
