....11 discusses how these results reflect on the learning method. Before proceeding, a note about the use of automata to describe harmonies: I have chosen not to adopt an autosegmental approach to harmony, even though this is the standard approach in phonological literature (Archangeli, 1985; Archangeli Pulleyblank, 1989; Clements Sezer, 1982; Goldsmith, 1976; Goldsmith, 1989; Katamba, 1984; Kaye, 1983; McCarthy, 1984; Spencer, 1986) What autosegmental analyses have in common is the view of harmonisation as a result of the autosegmental process of spreading. Where they differ markedly is in their treatment of ....

The vowel inventory of Yoruba includes seven oral and three nasal vowels 6 . These ten vowels are given in (56) together with a feature decomposition based on the one given by Archangeli and Pulleyblank. 56) i e e . a ....

....R with the redundant specification F. F is redundant here bevause the extension of R is a proper subset of the extension of F: all segments with property R also have property F. The idea of using a redundancy rule in interaction with floating autosegments and spreading rules was explored by (Archangeli Pulleyblank, 1989) in an analysis of Yoruba. The extensional interpretation of (57c) requires some understanding of the role Archangeli and Pulleyblank gave to the redundancy rules. According to the Redundancy Rule Ordering Constraint (Archangeli, 1984) redundancy rules apply to fill in features before the ....

....limitation of the framework, and the definition of of underspecification theory presented here could be applied to autosegmental representations if suitable types and functors were defined for them. In UT, lexical specifications are made in terms of an a priori fixed set of features. For example, Archangeli Pulleyblank (1989) use the four features [ Sigmahigh] Sigmalow] Sigmaback] and [ SigmaATR] to describe seven Yoruba vowels. All lexical specifications of vowel quality are assumed to involve specifications for some subset of these features. In the lexical specifications, redundant information is left ....

....In UT, redundant features are are filled by rule. Special constraints, such as the Redundancy Rule Ordering Constraint (Archangeli, 1984, 85) ensure that redundancy rules apply before the features they instantiate are referred to. Furthermore, these constraints apply as often as necessary (Archangeli Pulleyblank, 1989, 209 210) This has the same effect as the automatic specification of redundant feature values in the current framework. Only one type of feature value is ever lexically specified in UT. Opposite feature values are filled in by default rules. This allows the feature specifications for some ....
