Contrast and Phonological Activity in Manchu Vowel Systems

Abstract

AbstractIn the Manchu languages, contrast plays an important role in the patterning of vowel systems. Contrastive feature values are phonologically active, triggering rules of Advanced Tongue Root (ATR) and labial harmony, whereas redundant feature values are phonologically inert. To determine which feature values are contrastive in any given segment, it is necessary to establish an ordering of features. This ordering, or contrastive hierarchy, determines the relative contrastive scope of each feature. Our analysis of the Written Manchu contrastive hierarchy is supported by synchronic and diachronic evidence from Spoken Manchu and Xibe, where a realignment of vowel contrasts results in new patterns of phonological activity. We show that our analysis is consistent with the observed typology of ATR and labial harmony systems. We argue that the concept of phonological contrast does not reduce to a phonetic function, nor is it perceptually based. The relationship between contrast and underspecification is considered, and it is shown that constraint-based theories (such as Optimality Theory) do not constitute alternatives to the theory of contrast proposed here.
