Abstract

This paper investigates multichannel speech enhancement for colocated microphone recordings based on Independent Component Analysis (ICA). Comparisons are made between co-located microphone arrays that contain microphones with mixed polar responses with traditional uni form linear arrays formed from omnidirectional microphones. It is shown that polar responses of the microphones are a key factor in the performance oflCA applied to co-located microphones. Results from PESQ testing show a significant improvement in speech quality of ICA separated sources as a result of using an A VS rather than other types of microphone arrays.
