<p>In a DVE, digital voice enhancement (550), communication system, the selection decision for choosing which microphone to be active is based on a given function of the speech of a respective talker relative to his/her acoustic environment at the respective microphone. The selection decision is based on a selection technique normalizing at least one of a) different microphone sensitivities (580, 582, 584, 586) and b) different background noise levels (588, 590, 592, 594) at the respective microphones, preferably based on the ratio of how much louder a talker speaks over the background noise at his/her respective microphone.</p> |
