| 摘 要： | 从男性、女性的静态美尔倒谱系数（Mel-frequency cepstral coefficients），MFCC）特征概率密度函数的峰值差异、平均值和方差等方面研究了静态MFCC特征的性别差异性．结果表明，在峰值方面，MFCC1、MFCC2、MFCC6、MFCC9和MFCC12的差异最大；在均值方面，男性MFCC特征分量大于女性MFCC特征分量；在方差方面，大部分男性MFCC特征分量小于女性MFCC特征分量．

| Abstract: | To study gender differences of static Mel-frequency cepstral coefficients （ MFCC）, peak differences,mean and variances of static MFCC＇ s probability density was tested. The results showed that MF- CC1 ,MFCC2,MFCC6,MFCC9 and MFCC12 had more differences in peak differences, the male MFCC mean was more than female＇ s, and most of male MFCC covariance was less than female＇ s. |
