5. SUMMARY AND CONCLUSIONS
</SectionTitle>
    <Paragraph position="0"> LexPhon, a computational framework for models of lexical phonology, has been described and an example application of one potential use of such a system has been presented.</Paragraph>
    <Paragraph position="1"> Using LexPhon, contrastive L P structures were applied to Spanish and English data in the context of languagedependant Phoneme Inventories and Phonological Rule sets.</Paragraph>
    <Paragraph position="2"> A hypothesis was tested that intm-speaker style variation might be the result of applying the same rules to the same underlying forms but at different stages of the utterance formation process. In the case of the Spanish data for the Mexico City dialect, allocation of rules to strata appears to account for a substantial proportion of the attested variation between the speech speed styles. For the contrastive study of English careful versus ~tsual style data, re-allocation of rules to strata appears to account for a smaller proportion of the variation attested, in spite of the use of a much more comprehensive rule set.</Paragraph>
    <Paragraph position="3"> Although the studies presented here are not conclusivei they provide evidence which gives support to the theory that aspects of style variation may be attributable to the level of word-formation at which phonological rules are applied, rather than necessarily to differences in the formulation of the rules themselves. This supports the LP hypothesis that complex surface phonology of languages may be the result of interactions between relatively simple morphological and phonological processes taking place within a simple framework.</Paragraph>
    <Paragraph position="4"> Further, the application of LexPhon to a problem requiring alternative phoneme inventory, phonological rulebase and LP control framework demonstrates the flexibility which the system can offer to comparative studies in lexical phonology.</Paragraph>
