7. CONCLUSION
</SectionTitle>
    <Paragraph position="0"> In summary, disfluencies occur at high enough rates in human-computer dialog to merit consideration. In contrast to earlier approaches, we have made it our goal to detect and correct repairs automatically, without assuming an explicit edit signal. Without such an edit signal, however, repairs are easily confused both with false positives and with other repairs. Preliminary results show that pattern matching is effective at detecting repairs without excessive overgeneration. Our syntax-only approach is quite accurate at detecting repairs and correcting them. Acoustics is a third source of information that can be tapped to provide corroborating evidence about a hypothesis, given the output of a pattern matcher.</Paragraph>
    <Paragraph position="1"> While none of these knowledge sources by itself is sufficient, we propose that by combining them, and possibly others, we can greatly enhance our ability to detect and correct repairs. As a next step, we intend to explore additional aspects of the syntax and semantics of repairs, analyze further acoustic patterns, and examine corpora with higher rates of disfluencies.</Paragraph>
