    <Paragraph position="0"> Our study of the cue phrase now strongly suggests that speakers and hearers can distinguish between cue and non-cue uses of cue phrases intonationaUy, by making or noting differences in accent and phrasing. Cue and non-cue now in our samples are reliably distinguished in terms of whether now forms a separate intermediate or intonational phrase, whether it occurs first in its intonational phrase, and whether it is accented or not -- and, if accented, the type of accent it bears. In the absence of akernate known means of distinction between cue and non-cue use, we propose that speakers and hearers do differentiate intonationally. Our next step is to extend our study to other cue phrases, including anywm), well, first, and right. We also plan to examine the relationship between cue usage and pitch range manipulation \[7\], another indicator of discourse structure. The goal of our research is both to provide new sources of linguistic information for work in plan inference and discourse understanding, and to permit more sophisticated use of intonational variation in synthetic speech.</Paragraph>
