Adaptive English Speech Enhancement Based on ISD Optimized SSA-VMD Algorithm
Due to traditional speech enhancement methods have the problems of filtering out effective signals and poor enhancement performance,an adaptive English speech signal enhancement method based on ISD optimized SSA-VMD param-eters is proposed.Firstly,the SSA-VMD algorithm is used to adaptively obtain the optimal combination of VMD key param-eters for the input speech signal,and then it is decomposed to obtain each modal component.The similarity between each modal component and the input signal is evaluated based on the ISD principle,and then the noise modal components are se-lected,and the noise is reduced by wavelet threshold method.Finally,the signal is reconstructed to obtain enhanced speech.The experimental results show that using the proposed method to process English speech signal,the SNR is higher,the MSE is smaller,and the speech enhancement effect is more obvious,which has good applicability.
