Zusammenfassung User models have become increasingly popular to conduct simulationbased testing of spoken dialog systems. These models usually describe users' overt behavior, as opposed to the underlying reasons for the observed actions. While such models are useful to generate test data, a causal model might be more generally applicable to different systems, and in addition allow to derive useful information for data analysis and prediction of user judgments. Thus, a modeling approach trying to explain user behavior is proposed in this paper, which is based on D¨orner's PSI theory. The evaluation shows that the utterances generated by this model are similar to those of real users.
