심리음향적 제약조건 최적화에 기반한 잡음 제거 기법

Abstract

This paper considers a speech enhancement based on the psychoacoustically constrained and distortion minimized problem. In this paper, a constrained optimization problem is set to minimize speech distortion while both speech distortion and residual noise keeping below the masking threshold of the clean speech. Experimental results show that the performance of the algorithm considered in this paper is better than some of the more popular algorithms.
