Abstract

Abstract: Aiming at low calculation accuracy of MFCC feature parameters for speech recognition in high-frequency signals，this paper adopts the combination algorithm of IMFCC，MIDMFCC，MFCC，which uses a mixture of filter banks to enhance high-frequency calculation accuracy in the calculation accuracy.The experiments result shows that the recognition rate of improved algorithm increases compared to the classical algorithm in the same environment.

摘要： 针对MFCC特征参数在语音识别中对中高频信号的识别精度不高的特点，提出采用IMFCC，MIDMFCC，MFCC相结合的改进算法，使用混合滤波器组，提高在语音中高频区域中的识别精度。实验结果表明，改进之后的算法与经典算法比较，在相同环境下对语音信息的识别率都有一定程度的提高。
