A Family of Coherence-Based Multi-Microphone Speech Enhancement Systems

A Family of Coherence-Based Multi-Microphone Speech Enhancement Systems

This contribution addresses the problem of additive noise reductionin speech picked up by a microphone in a noisy environment. Two systemsbelonging to the family of coherence-based noise cancellers arepresented. Suggested systems have the modular structure using 2 or 4microphones and suppress non-st...

Suggested systems have the modular structure using 2 or 4microphones and suppress non-stationary noises in the range of 4 to 17dB depending on the chosen structure and noise characteristics. Thecommon properties are acceptable noise suppression, low speechdistortion and residual noise.www.radioeng.cz/fulltexts/2003/03_02_23_30.pdf
