Abstract

The purpose of this paper is to improve the perceptual quality of a single channel speech enhancement algorithm using MMSE LSA estimator. The proposed algorithm uses a non-linear decision rule and an adaptive recursive averaging factor for tracking a priori speech absence probability (SAP) fast. We also introduce one-third of approximated critical bandwidth to efficiently smooth the a priori SAP and final gain term, which successfully eliminates the musical noise without much distortion of signal. The performance of the proposed algorithm is evaluated by performing subjective A/B listening tests and measuring spectral distance. Simulation results verify the effectiveness of the proposed algorithm compared to conventional algorithms.
