    <Paragraph position="0"> In this paper we presented the results of a corpus study of naturally occurring CRs in task-oriented dialogue. Comparing our results to two other studies, one of a task-oriented corpus and one of a cor- null pus of everyday conversation, we found no significant differences in frequency of CRs and distribution of forms in the two task-oriented corpora, but many significant differences between CRs in task-oriented dialogue and everyday conversation. Our findings suggest that in task-oriented dialogues, humans use a cautious, but efficient strategy for clarification, preferring to present an hypothesis rather than ask the user to repeat or rephrase the problematic utterance. We also identified correlations between function and form features that can serve as a basis for generating more natural sounding CRs, which indicate a specific problem with understanding. In current work, we are studying data collected in a wizard-of-oz study in a multi-modal setting, in order to study clarification behavior in multi-modal dialogue.</Paragraph>
