维吾尔语的内爆音

Implosives in Uyghur

我们的田野调查发现,维吾尔语有内爆音。通过语音分析得出:1.词首浊塞音有三种自由变体即内爆音、一般浊塞音、清不送气塞音,其中一般浊音的比重极少。元音间的浊塞音有两种变体内爆音和一般浊塞,其中内爆音比重极少;2.PCquirer测得词首内爆音的口压等于或大于大气压,因此负口压不是判断内爆音的必要条件;3.内爆音早就存在,目前正处于自由变体阶段。

This paper presents the first report on implosive stops in Uyghur. First, it is discovered that voiced stops in word initial positions have three free variants： implosives, plain voiced stops, and voiceless unaspirated stops, with voiced allophones occurring least, and bilabial implosives being the highest in frequency, while on the other hand, for intervocalic voiced stops only two free variants may occur, viz. voiced stops and implosives, with implosives occurring less. Then, it argues that negative oral pressure is not an essential criterion for implosives, as the oral pressure measured for initial implosives is equal to or higher than the atmospheric pressure during the closure of implosives. Last, it proposes that implosive allophones are not the result of contact-induced sound change but rather a sound change developed from some earlier stage of Uyghur.
