AM-FM model of gravity tide IMF and its non-linear data fitting
重力固体潮IMF的AM-FM模型及其非线性拟合
Secondly, motivated by the obvious nonlinear phenomena in the process of speech generation, through the in-depth study of nonlinear AM-FM model, weighting method of improved MFCC feature coefficient is proposed.
从基于特征的角度出发：首先根据人耳对不同频段的感知程度不同,提出了结合人耳响度特性的子带分频加权算法来降低噪声对MFCC的影响,加权的原则是对识别贡献率较大的子带赋予相对较高的权值,反之则赋予相对较低的权值；其次,针对语音产生过程中存在的非线性现象,通过对非线性AM-FM模型的深入研究,本文提出了改进的MFCC特征系数加权算法,使用该算法提取的MFCC特征能有效利用语音信号中的幅值包络和瞬时频率信息,同时又兼顾了耳蜗子带分频特性,使系统的识别率有一定的提高。
