1. INTRODUCTION
</SectionTitle>
    <Paragraph position="0"> In this paper we report on our work on a spoken language navigation system which runs in real-time on a high-end laptop or PC, for use in a vehicle. We focus on issues in developing a system which can understand natural conversational queries and respond in such a way as to maximize ease of use for the driver.</Paragraph>
    <Paragraph position="1"> Because today's technology has the potential to deliver massive amounts of information to automobiles, it is crucial to deliver this information in such way that the driver's attention is not diverted from the primary task of safe driving. Our assumption has been that a dialogue system with a near-human conversational ability would place less of a cognitive load on the driver than one which behaves very differently than a human.</Paragraph>
    <Paragraph position="2"> We have implemented a testbed on which to develop and evaluate driver interfaces to navigation systems. Our approach is multi-modal and the interface will include a head-up display, steering hub controls, and spoken language, though it is only the latter modality that we report on here. We first discuss our development phases, and after this we provide an overview of our implementation, emphasizing the natural language processing aspects and application interface to the map databases. Next we provide results of our initial evaluation of the system, and finally we draw conclusions and summarize plans for future work.</Paragraph>
