In recent years, sparse representation is adopted to improve the quality of noise corrupted speech. However, the representation of noise is also found to be sparse in some special cases, which degrades the performance of sparsity based speech enhancement. An adaptive speech enhancement algorithm using sparse prior information is proposed in this paper. In the proposed method, speech enhancement is casted to an optimization problem, where linear prediction (LP) residual and DCT coefficients are… CONTINUE READING
