Acoustic analyses were undertaken to explore the durational characteristics of the fricatives [f,theta,s,v,delta z] as cues to initial consonant voicing in English. Based on reports on the perception of voiced-voiceless fricatives, it was expected that there would be clear-cut duration differences distinguishing voiced and voiceless fricatives. Preliminary results for three speakers indicate that, although differences emerged in the overall mean duration of voiced and voiceless fricatives, contrary to expectations, there was a great deal of overlap in the duration distribution of voiced and voiceless fricative tokens. Further research is needed to examine the role of duration as a cue to syllable-initial fricative consonant voicing in English.
进行声学分析以探究擦音[f,θ,s,v,ð,z]的时长特征,将其作为英语中词首辅音浊音化的线索。基于有关浊音和清音擦音感知的报告,预计会有明显的时长差异来区分浊音和清音擦音。三位说话者的初步结果表明,尽管浊音和清音擦音的总体平均时长出现了差异,但与预期相反,浊音和清音擦音音素的时长分布有大量重叠。需要进一步研究以考察时长作为英语中音节首擦音辅音浊音化线索的作用。
