6 Conclusion
</SectionTitle>
    <Paragraph position="0"> The primary contribution of this work is that it treats misunderstanding and repair as intrinsic to conversants' core language abilities, accounting for them with the same processing mechanisms that underlie normal speech. In particular, it formulates both interpretation and the detection of misunderstandings as explanation problems and models them as abduction.</Paragraph>
    <Paragraph position="1"> We have implemented our model in Prolog and the Theorist framework for abduction with Prioritized defaults. Program executions on a Sun-4 for four-turn dialogues take 2 cpu seconds per turn on average.</Paragraph>
    <Paragraph position="2"> Directions for future work include extending the model to handle more than one communicative act per turn, misunderstood reference \[Heeman and Hirst, 1992\], and integrating the account with sentence processing and domain planning.</Paragraph>
