In this paper we present a speech enhancement method in highly non-stationary noise environments based on modified Improved Minimal Controlled Recursive Averaging (IMCRA) method and Optimal Modified Minimum Mean-Square Error Log-Spectral Amplitude (OMLSA) method. The original OMLSA method, the spectral gain function, which minimizes the mean-square error of the log-spectral amplitude, is obtained...
This paper proposes an algorithm improved over MMSE-LSA Algorithm. It suits non-stationary noise environments better than the traditional algorithm. The main part of this method is the estimation of noise, which is updated using time-frequency smoothing factors calculated based on speech-present probability in each frequency bin of the noisy speech spectrum. It could keep up with the noise change...
