彝语全浊音的语音分析

An Acoustic Analysis on the Voiced Consonants in the Yi Language

本文用实际录音材料分析了彝语全浊音声母的基本声学特征。分析的初步结果为,彝语浊音保留比较完整,浊声杠较长,发音清晰;浊爆音有常态浊音和内爆音等表现形式,它们是同一音位的不同变体;浊音的音强一般高于同部位的清音;浊音对后接元音前过渡第一共振峰有一定影响,其后接元音前过渡第一共振峰一般低于同部位的清音,但浊音对后接元音第一共振峰影响不大。

Based on recorded language materials, this paper analyzes the basic acoustic characteristics of the voiced consonants in the Yi language. The preliminary results obtained are as follows： the voiced consonants in the Yi language remain relatively intact, showing long and evident voice bars in the spectrograms. For voiced plosives, there are plain voiced ones and implosives, which are allophonic. The sound intensity of voiced consonants is generally louder than that of their voiceless counterparts of the same places of articulation. The voiced consonants have a certain influence on the pre-transition of F1 of the following vowels, which is generally lower than that of vowels after the voiceless consonants of the same places of articulation, but on the other hand, the voiced consonants have less effect on the F1 of the following vowels.
