摘要 从说话人的语音信号中提取出能反映其个性特征的参数是声纹识别的关键环节之一。介绍了MEL倒谱系数(MFCC)及其提取方法,在此基础上提出了一阶差分(△MFCC),并将MFCC和△MFCC结合起来作为声纹识别的参数进行了MEL参数提取实验。实验结果表明将MFCC和△MFCC结合起来作为特征参数在识别性能上优于独立的MFCC。 The extraction of parameters reflecting the characteristics of speaker's speech signal is the key to voiceprint recognition.MEL cepstrum coefficient(MFCC) and extraction method was introduced in this paper.On this basis,the first difference(△MFCC) was put forward.MFCC and △MFCC were combined to conduct an experiment of parameter extraction from voiceprint recognition.The results show that the extraction combining MFCC with △MFCC is superior to the independent MFCC.
