5 Conclusion
</SectionTitle>
    <Paragraph position="0"> With our approach we unify some of the efforts outlined in 4.1 and come up with a system that is more clearly structured than the &amp;quot;algorithmic&amp;quot; approach.</Paragraph>
    <Paragraph position="1"> By basing our work on GToBI - and thus on a variant of Pierrehumbert's model on intonation - we have access to the wealth of phonological research undertaken in the tone sequence paradigm.</Paragraph>
    <Paragraph position="2"> The handling of accentuation and phrmsing by the generator resembles the syntacto-semantic approaches. Only a few tags such as emphasis \[EMPH\] and (conceptual or textual) givenness \[GIVENJ which are rather easily identifiable by the conceptual component and have a straight-forward influence on the phonetic realization are used. In this respect our approach is less refined than, e.g., (Prevost &amp;: Steedman 94) as no fully fledged semantic module is integrated that could deal with aspects of information structure in a really principled way On the other hand we employ a very flexible and transparent phonological model. But not all intonation contours that can be observed in human speakers are equally convenient for the use in synthetic speech, where the deviations in duration, amplitude, etc. may lead to results that are perceived as highly unnatural. We thus restrict the set of possible contours licensed by the GToBI to a simplified subset.</Paragraph>
    <Paragraph position="3"> The system is implemented and deals with the task of generating monologuous weather re.ports. null</Paragraph>
