摘要： 目的研究在话者识别领域,不同频率共振峰特征价值的大小。方法对10对女性与8对男性双胞胎正常朗读语音的共振峰频率特性进行定量测量、比较、分析,统计。结果男性和女性双胞胎个体依据2000Hz以下、2000-5000Hz、5001-8000Hz不同频率范围内的共振峰均可区分,但共振峰的缺峰比例随着频率的升高而升高,5001-8000Hz范围的缺峰比例达26.67%。结论不同频率共振峰在话者识别中的区别能力无显著差异。

Abstract: Objectiv To study the discriminating value of different frequency formants in voice identification.Methods Formants of 10 female and 8 male twins'natural reciting speech were measured, discrimination value and stability of which were compared and analyzed.Results whether female or male twins could be discriminated based on the formants in the different frequency ranges, including lower than 2 000Hz, 2 000Hz-5 000Hz and 5 001Hz-8 000Hz.Stability of formants were decreased with the increasing of frequencies and the proportionf of nulli-formants was as higher as 26.67% in the range of 5000Hz-8000Hz.Conclution The discriminating value of formants within different frequency ranges was no significant difference due to the influence of the stability of formants.

Key words: speaker recognition, Formant Frequency, discriminating value
