Abstract

This paper presents a robust system to improve speech signals processed by communication systems. The system includes multi-microphone techniques, for which both spectral and spatial characteristics of the signal sources can be used. Also a spectral subtraction algorithm for noise reduction is integrated into the system. The modified spectral subtraction method takes into account the non-uniform effect of colored noise on the speech spectrum and improves the multi-microphone noise filtering.

Keywords: Speech enhancement Multi-microphone noise reduction
