话者鉴别的一个基本前提是“个体间的语音差异大于个体的语音变异”。为了考察这一 前提对遗传基因、社会环境等因素高度相似的双胞胎个体是否适用,本文对18对双胞胎正常朗 读语音的共振峰频率特性进行了定量测量、比较、分析,总结了双胞胎个体间语音的差异程度, 得出一些对双胞胎正常语音共振峰频率特性差异性的认识。 One of the basic prerequisites for speaker identification is that “the voice difference between individuals is greater than the individual’s voice variation.” In order to investigate whether this premise is suitable for twins with similar genetic factors and social environment factors, this paper quantitatively measured the formant frequency characteristics of 18 pairs of normal reading speech of the twins, and compared, analyzed and summarized the speech of twins Differences, come to some understanding of the differences in the frequency characteristics of the normal voice formant twins.
