Abstract
A method of processing microphone signals generates a specified or required multichannel microphone input for a voice recognition system. The method comprises receiving first and second microphone signal from first and second microphones that have a spacing that is required by a voice response or recognition system. The first and second microphone signals are processed using at least one additional microphone signal to generate a first modified microphone signal and a second modified microphone signal respectively. The first and second modified microphone signals are then provided as required microphone inputs to a voice response or recognition system.
