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。
In this paper, we analyze the basic acoustic features of the Yi voiced initial consonants using the actual recording material. The preliminary results of the analysis are as follows: Yi voices retain relatively complete voices, while voiced voices are longer and pronounced clearly; voiced sonic explosives have the forms of normal dullness and implosion, which are different variations of the same phoneme; the sound intensity of dullness is generally high At the same place, the unvoiced voiced voiced voice had a certain influence on the first formant transition before the subsequent vowel transition, followed by the first formant transition before the vowel was generally lower than the unvoiced voice of the same place, Formant little effect.
