Abstract

High quality of transmitted signals is the most important task in communication when using mobile telephone, even in complicated challenging situations with presence of third-party speaker, transport vehicle, diffuse noise field, imperfect propagating of acoustic sound. Microphone array (MA) processing has become attractive technology for noise suppression in acoustic audio device by utilizing the spatial information, the properties of geometry MA, the direction-of-arrival (DOA) of interest signal without speech distortion of useful signal. GSC beamformer is one the most popular method, which applied in almost acoustic device for extracting target speaker and suppress noise from different directions. However, in realistic scenario, the error of phase or microphone mismatches often lead to speech leakage in the reference signal, that significantly deteriorates the performance of GSC beamformer, decrease the speech quality of final signal. In this paper, the author proposed a spectral mask for alleviating the speech leakage at the output of BM block to improve speech quality of GSC beamformer. Experimental results show the effective usage of suggested method (GSC-sp) in comparison between conventional GSC beamformer (GSC-ctl) and GSC-sp. Numerical results ensures that the author’s approach can be integrated into multi-microphone system for solving other complicated tasks in practical situations and increases the signal-to-noise ratio to 2:3 (dB).
