摘　　要：为探究音强包络面积相对比识别双胞胎同胎个体的可行性,文章利用语音音节音强包络曲线面积的相对比值,对14对同卵双胞胎同胎个体的语音进行了定量统计实验研究。实验结果表明,在90%、95%、98%的置信度下,实验所用的双胞胎同胎个体能够较好地被识别开来。进而得出,语音音节音强包络曲线面积的相对比值可以作为识别同卵双胞胎同胎个体的有效参量。To research the feasibility of identical twin recognition through comparing the envelope areas of sound intensity,this study conducted a quantitative experiment on speech sounds of 14 identical twins based on the comparing value of the sound intensity envelope areas.Results show that when confidence is 90%,95%or 98%,the identical twins in the study can be better distinguished and identified.Therefore,the comparing value of sound intensity envelope areas can be used as one of the effective parameters for identical twin recognition.
