摘要
目的研究不同通信系统条件下,利用语音进行说话人识别的基本假设"个体之间的语音差异大于个体自身的语音变异"是否成立。方法选择宽带语图差异较大的不同通信系统下语音进行比对及差异的统计。结果发现说话人识别的基本假设在不同通信系统条件下成立。结论得出了不同通信系统条件下进行说话人识别的方法与判阈。
Objective To validate the basic premise of voice identification, that is, inter-speaker difference of voice is bigger than intra-speaker variation, under different communication systems.Methods Broad band spectrograms of voices under different communication systems were compared.Results The basic premise of voice identification is valid under different communication systems.Conclusion Knowledge about voice identification under different communication systems was obtained.
