维吾尔语元音和谐的自主音段分析

An Autosegmental Approach to Uyghur Vowel Harmony

维吾尔语的元音和谐与许多其他语言的元音和谐一样,其中性元音的不和谐性一直是难以合理解释的焦点。根据自主音段音系学理论,文章认为维吾尔语和谐元音的[后位性]特征是词库项的固有信息,维吾尔语元音和谐的音系机制是底层词库项中自主音段[后位性]成分与底层没有赋值[后位性]特征的元音音段联接的"填充"。根据不充分赋值理论,[后位性]特征对维吾尔语的中性元音表现为不充分赋值,因此它们既无需从自主音段获取[后位性]特征,也不阻断其他元音对[后位性]特征的获取。这就是维吾尔语中性元音不和谐性的音系理据。

Like the vowel harmony in many other languages,Uyghur vowel harmony also has the disharmony of neutral vowels which remains an unsolved problem in phonological studies cross-linguistically.Based on the autosegmental theory,this paper argues that the harmonic feature of backness in Uyghur vowel harmony is inherent lexical information and that the ＂feature filling＂ by associating the autosegment in lexicon with the vowels unspecified for backness in a word serves as the phonological mechanism of Uyghur vowel harmony.In light of underspecification theory,the paper also claims that Uyghur neutral vowels are underspecified for backness,so they do not need backness feature from the autosegment;neither do they block the association of with other vowels in a word,which is the phonological motivation for the disharmony of the neutral vowels in Uyghur vowel harmony.
