| 摘 要： | 语音识别中,倒频谱是识别效果最好的一种参数.而语速的变化对于识别效果有着很大的影响,因此研究不同语速对于倒频谱的影响是很有意义的一项工作.计算并对比了两种语速(快速与慢速)下部分元音和辅音的倒频谱中C0值、C1值、峰值位置与峰值幅度值特征,给出了实验结果,以期探讨语音倒频谱在不同语速下的一些特点.

| Abstract: | The cepstrum is one of the best parameters used in the speech recognition, while the variance of speech rate has vital influence on speech recognition effect. Therefore, it is significant to investigate what influence the variance of speech rate has on the cepstrum. In this paper,the C0,C1 ,peak place and peak magnitude of cepstrum of some vowels and consonants with different speech rate are computed and compared to explore some characteristics of them with respect to speech rate. Moreover, The wave of vowel in one fundamental period and its cepstrum are contrasted. |
