The Division of Labor between Segment-internal Structure and Violable Constraints

This paper touches on a range of conceptual and practical issues that are relevant to current discussions regarding the nature of the phonological component of the grammar, including: featural, representational and constraint economy; representation versus evaluation; computation versus competence; the line between phonetics and phonology; categorical perception; full-specification of features versus minimal/contrastive specification; richness-of-the-base; the infinite candidate set; universality of constraints; the lexicon; and phonological acquisition. The paper begins with a review of several conceptual issues, highlights some interesting general problems and possible solutions (necessarily abridged due to space considerations), and then moves on to a detailed discussion of how one might model the segment inventory (including phonetic dispersion and variation) of a specific language in Optimality Theory (Prince and Smolensky 1993).
