Prosodic entrainment in dialog acts
This research addresses how prosodic features vary in human communication based on game type and dialog act properties, which is incremental in understanding social interactions.
The study investigated prosodic entrainment in spoken dialogs across different dialog acts in cooperative and competitive games, finding that in cooperative games, dialog acts with high authority and frequency showed the most entrainment.
We examined prosodic entrainment in spoken dialogs separately for several dialog acts in cooperative and competitive games. Entrainment was measured for intonation features derived from a superpositional intonation stylization as well as for rhythm features. The found differences can be related to the cooperative or competitive nature of the game, as well as to dialog act properties as its intrinsic authority, supportiveness and distributional characteristics. In cooperative games dialog acts with a high authority given by knowledge and with a high frequency showed the most entrainment. The results are discussed amongst others with respect to the degree of active entrainment control in cooperative behavior.
