Abstract

A wireless audio monitor can remotely detect voice activity. A first portable radio transceiver 60 is reversibly switchable between a first narrow bandwidth audio receiving mode and a second wide bandwidth audio receiving mode. The first transceiver 60 is adapted to operate in the first narrow bandwidth audio receiving mode when listening for voice activity, and to communicate with a second transceiver 64 in wide bandwidth mode via a radio communication link when voice activity has been detected. The second transceiver 64 is adapted to indicate to a user the detection of voice activity by the first transceiver 60. The detection of voice can be optimised for infant voices 52, to enable the system to function as a baby monitor.
