沁县方言中的[i] > [？ ]
[i] > [？ ] in Qinxian Dialect

本文以沁县松交话和城关话为研究对象，发现松交话和城关话是沁县方言中[i] > [？]的两个不同的阶段，是共时层面的不同，且城关话[i]的高化程度要高于松交话；接着解释其形成动因在于舌面高元音[i]的发音部位向前，发音方法上高化产生了摩擦而引起的音变现象，是摩擦化以后进一步高化的结果。最后揭示了这种音变的性质属于拉链式音变，是蟹止摄开口三四等字主要元音不断高化，[i]演变为[？]后，留下了空格，这个空格为了保持语音系统的相对稳定性，就“拉动”咸山摄开口二三四等字韵母高化为[i]韵以填补这个空位。
This paper takes Qinxian Songjiao dialect and Chengguan dialect as the research object. It is found that Songjiao dialect and Chengguan dialect are two different stages of [i] > [？] in Qinxian dialect. They are different in synchronic level, and Chengguan dialect [i] is higher than Songjiao dialect. Then it is explained that the reason for its formation is that the pronunciation part of the high vowel [i] on the tongue surface is forward, and the phonetic change phenomenon caused by the friction of the pronunciation method is the result of the further elevation after the friction. Finally, it is re-vealed that the nature of this sound change is zipper sound change, which is that the main vowel of the three and four characters of the crab shot opening is constantly elevated, and [i] is transformed into [？], leaving a space. In order to maintain the relative stability of the phonetic system, the vowel of the two, three and four characters of the Xianshan opening is “pulled” to be elevated into [i] rhyme to fill this gap.
