Abstract: For the problem of low intelligibility and intelligibility of noisy mask speech, a method combining compressed sensing and Empirical Mode Decomposition （EMD） is proposed to enhance the performance of noisy mask speech. Firstly, the noisy mask speech is decomposed by EMD to obtain the intrinsic mode function signal components, and specific intrinsic mode component are denoised by wavelet threshold. Then all signal components are compressed sensing and reconstructed to enhance the noisy mask speech. The experimental results show that the proposed method has good denoising effect, small reconstruction error and high stability, and effectively realizes the enhancement of mask speech.
