SUMMARY
</SectionTitle>
    <Paragraph position="0"> This paper gives a current status of our ATIS development effort. A significant change since the last workshop is that the system can now accept verbal input. We have also rewritten the back-end component, adopting an approach that should promote extension and portability. We have extended our evaluations this time to include both Class A and Class D1 sentences. Our evaluations for both speech and text input were performed on two different data sets, collected at TI and MIT. The system's performance appears to depend strongly on the conditions under which the data were collected.</Paragraph>
