浙江仙居吴语浊内爆音的语音学考察

A Phonetic Study on the Voiced Implosives in Wu Dialect of Xianju County,Zhejiang Province

经综合分析语音信号和喉头仪信号,本文揭示了浙江仙居吴语浊内爆音的语音学表现:(1)声学上以持阻段声波振幅渐增为典型特征。(2)喉头仪信号的开商值揭示其嗓音特性偏向于紧喉发声态。(3)浊内爆音与鼻音在低频段具有相似的共振峰,这可能是浊内爆音鼻音色彩的来源。就共时平面看,浊内爆音并不与普通浊塞音形成对立,内爆为羡余特征,因此浊内爆音有可能引起新的音变。

Based on theacoustic signals and data collected through Electroglottography （EGG）, this paper describes the acoustic features of the voiced implosives in Wu dialect of Xianju county in Zhejiang province, specifically, 1 ） The typical phonetic feature is that the vibration amplitude of the wave of the stop section is increasing; 2） The open quotient （OQ） of the EGG data reveals that the voice feature of the voiced implosives is similar to creaky phonation; 3） Voiced implosives and nasals share similar formants on the low-frequency stage which may reveal the source of the nasality of voiced implosives. Synchronically, voiced implosive is not a phonemic contrast to voiced stop and therefore ingressive is actually a redundant feature. The voiced implosive may cause new phonetic changes.
