Abstract

Abstract: The basic premise of speaker identification is that the interspeaker difference is bigger than the intraspeaker variation. We measured, compared and analysed the formant relative amplitude of 30 pairs of twins' natural reciting voice, and counted the confidence level and discriminating threshold.

Key words: twins' voice, speaker identification, formant relative amplitude

摘要： 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”。本文对30对双胞胎正常朗读语音的共振峰强度特性进行了定量测量、比较、分析,统计得出了共振峰相对强度特性在检验双胞胎语音中的置信度与判阈。

关键词: 双胞胎语音, 话者鉴别, 共振峰相对强度特性
