Speech Enhancement Using Multiple Soft Constrained Beamformers and Non-coherent Technique

Low, Siow-Yong; Grbic, Nedelko LU and Nordholm, Sven (2003) IEEE International Conference on Acoustics, Speech and Signal Processing, 2003 In IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings.(ICASSP'03). 5. p.489-492
Abstract
This paper presents a new robust microphone array processing technique to enhance speech signals under the influence of noise and jammer(s). The new structure comprises two soft constrained subband beamformers and a non-coherent processing technique. Essentially, the first beamformer enhances the desired speech signal in a specified constrained region. The residual interference in the beamformer's output is then spectral subtracted using the estimated interference from the second beamformer. Evaluations in a real office environment show higher interference suppression compared to those obtained using the soft constrained beamformer only. Most importantly, this is achieved with negligible expense on target signal distortion.
