伪装语音是司法语音检验领域常见的检材形式,给话者鉴别带来诸多困难。本文针对电声伪装语音,通过图谱和数据分析的方法得出多个语音库变声前后的基频变化规律,结果表明变声前后的基频存在着线性关系,可借助汉语音高模式比对的方法实现电声伪装语音的话者鉴别。 Disguised speech is a common form of prosecution in the field of judicial voice examination, which brings many difficulties to the speaker identification. In this paper, for the electroacoustic camouflage speech, the variation law of the fundamental frequency before and after the vocal change of many vocal libraries is obtained by the method of spectrum analysis and data analysis. The results show that there is a linear relationship between the fundamental frequencies before and after the vocal sound modification. Realize the voice of the masquerade voice identification speaker.
