元音串的處理：郡社布農語與賽考利克泰雅語的比較分析

Resolving Vowel Clusters: A Comparison of Isbukun Bunun and Squliq Atayal

本文檢視布農語郡社方言與泰雅語賽考利克方言如何處理因後綴加插而導致的元音串，探討其相似與相異之處，並提出理論上的分析。雖然這兩個台灣南島語言在音位及節律特色等方面頗有差異，在元音串的處理上，它們卻一致採滑音形成及元音融合兩種策略，不同之處僅在於滑音形成及元音融合發生的語音環境條件。本文認為這樣的差異其實和這兩個語言所允許的音節型態息息相關，文中並進一步闡述，相較於傳統衍生音韻學的架構中將陳述規律的重點放在音韻規則發生前的語音組合，以表層制約為基本機制的架構，例如優選理論，比較能夠直接捕捉音節型態與元音串處理方式的關連性。

The goals of this paper are to identify, compare, and account for the ways suffixation-induced vowel clusters are handled in Isbukun Bunun and Squliq Atayal, two Formosan Austronesian languages. Despite the fact that the two languages have distinct segmental inventories and prosodic characteristics, Isbukun and Squliq are shown to be strikingly similar in adopting both glide formation and coalescence to modify vowel sequences, and they differ in terms of the conditioning environments in which the two processes occur. The paper argues that such differences are correlated with the permitted syllable types in the two languages, and points out that the correlation can be explicitly captured in the output-oriented framework of Optimality Theory but not in a rule-based analysis that states generalizations based on input configurations.
