1 Introduction
</SectionTitle>
    <Paragraph position="0"> The approach to dialogue managenaent described here has been developed as part of the Sundial project (Speech UNderstanding in DIALogue) whose goal is to build real-time integrated computer systems capable of maintaining co-operative dialogues with users over standard telephone lines. 1 Systems have been developed for four languages - French, German, Italian and English - within the task domains of flight reservations and enquiries and train enquiries.</Paragraph>
    <Paragraph position="1"> Each system consists of five components: a speech recognition component inputs acoustic speech signals fi'om the telephone and outputs a word lattice; a parser extracts a plausible string from the lattice and assigns it syntactic and semantic representations; a dialogue manager gives these representations an interpretation, decides how the dialogue lnay continue and, if it is the system's turn to speak, plans a system utterance; a text.</Paragraph>
    <Paragraph position="2"> generator constructs a. detailed linguistic representation from the plan; and a text-to-speech system synthesizes the representation for transmissiol~ by telephone. '2</Paragraph>
