Extensive research about recovery strategies for misunderstandings and non-understandings within the context of spoken dialogue systems (SDS) has been undertaken in the past and is still going on. Many scientists focus on optimizing the recovery rate using various strategies. It is still not sufficiently explored, how different strategies relate to user satisfaction, and how confused users get with simple strategies such as a reprompt. We carried out an empirical analysis with some of the most promising strategies. In addition to the two common strategies help and reprompt we also evaluated an adapted version of the promising MoveOn strategy. We found that the reactions regarding our different mockup dialogues, especially between computer experts and novices, vary a lot.
