| 摘 要： | 文章在对应力影响下变异语音进行分频带分析的基础上,选用了可以提升语音信号中频段影响的修正Mel频率映射,并将其对应的MFCC系数作为新的语音识别特征。通过采用正常/变异语音分类器和新特征来进行变异语音识别。实验结果表明:采用修正Mel频率映射的MFCC特征改进了变异语音的识别性能。

| Abstract: | On the basis of analyzing the recognition of speech under G-Force by using each Mel-frequency scale,two kinds of modified Mel-frequency scales which can emphasize the effect of the middle frequency ranges are explored in this paper,consequently,the relative MFCCs are selected as the features for recognition of speech under G-Force.Using a classifier of stressed speech and the new features, some experiments are conducted, and it shows that the modified Mel-frequency are effective for stressed speech recognition. |
