英语非重读央元音的表达和推导
非重读央元音[ə],是英语中出现频率最高的元音,在英语语音系统中拥有着特殊的地位。从非重读央元音分别与非重读音节、元音弱化、弱读式、同化现象、省音现象和增音现象的关系这几个方面出发,沿用乔姆斯基等人对英语非重读央元音存在三个底层来源的假设,通过线性结构分析方法,对英语非重读央元音从底层表达到表层表达的推导过程进行了探讨。结果发现交替式非重读央元音的派生过程正是元音弱化为[ə]的过程,非交替式非重读央元音的派生过程容易受到同化和省音现象的影响,而插入式非重读央元音的派生过程解释了[ə]增音现象。

Representation and Derivation of Schwa in English
 
Abstract: Schwa [ə] is the most frequently used vowel in English and possesses a special status in English sound system. Based on the illustration of the relationships between schwa and unstressed syllable, vowel reduction, weak form, assimilation, elision and epenthesis respectively and Chomsky's hypothesis that the surface representations of schwa have three underlying sources, the present study aims to explore the derivation of English schwa from underlying representation to surface representation by means of liner analysis. The results indicate that the derivation of the alternating schwa is the process of vowel reduction to [ə]; the non-alternating schwa is apt to be influenced by assimilation and elision and the epenthetic schwa could account for the epenthesis of [ə].
Key words: schwa; vowel reduction; weak form; underlying representation; surface representation
