Prosodic entrainment in dialog acts

Abstract

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.

Prosodic entrainment in individuals with autism spectrum disorder

“…However, it must be noted that not all speech acts in a naturalistic dialogue serve the same function, which means that dialogue act type may affect entrainment during the interaction. For example, Reichel, Mády and Cole (2018) found that people show a greater tendency to entrain during collaborative dialogue acts than during competitive ones. The way entrainment is affected by dialogue act type, social factors such as collaboration, and the interaction between the two requires further investigation, both in individuals with and without ASD.…”
