摘　　要：小舌与软腭部位的清塞音有分布上互补或二者合并为软腭音的关系。按塞音的调音过程及其对后接元音的影响进程,分析桑孔语小舌和软腭送气、不送气清塞音的GAP和VOT特征、瞬时能量频谱和变化趋势,以及音轨方程和后接元音谐波能量差,发现桑孔语小舌软腭清塞音之间存在区别,但并不明显,而且小舌音有前移或软腭化的趋势。The voiceless uvularandvelar stops can distribute complementarily and uvular stops can merge into velar stops,which indicate that there are close relationships between the two groups of sounds. According to the articulation progress and the effects of the two groups of stops on the vowels following them, this paper analyses the voiceless uvular and velar aspirate and unaspirated stops in Sangkong Language by measuring GAP and VOT, FFT Spectral Slice and the Ltas trend line, locus equation,and the slope of spectrum, finding that there are not too much differences among the stops, and the uvular stops have tendencies of velarization.
