1. INTRODUCTION
</SectionTitle>
    <Paragraph position="0"> This paper describes and presents evaluation results for Talk'n'Travel, a spoken language dialogue system for making complex air travel plans over the telephone. Talk'n'Travel is a research prototype system sponsored under the DARPA Communicator program (MITRE, 1999). Some other systems in the program are Ward and Pellom (1999), Seneff and Polifroni (2000) and Rudnicky et al (1999). The common task of this program is a mixed-initiative dialogue over the telephone, in which the user plans a multi-city trip by air, including all flights, hotels, and rental cars, all in conversational English over the telephone. A similar research program is the European ARISE project (Den Os et al, 1999).</Paragraph>
