  abstract  = {Recent spoken dialog systems are moving away from command and control towards a
	more intuitive and natural style of interaction. In order to choose an
	appropriate system design which allows the system to deal with naturally spoken
	user input, a definition of what exactly constitutes naturalness in user input
	is important. In this paper, we examine how different user groups naturally
	speak to an automotive spoken dialog system (SDS). We conduct a user study in
	which we collect freely spoken user utterances for a wide range of use cases in
	German. By means of a comparative study of the utterances from the study with
	interpersonal utterances, we provide criteria what constitutes naturalness in
	the user input of an state-of-the-art automotive SDS.},
