Abstract: A microphone device comprises a transducer configured to convert sound energy into an electrical signal, a memory configured to store operational parameters for the microphone, and an application specific integrated circuit (ASIC) coupled to the transducer. The microphone is configured to receive a command requesting the operational parameters from a processing device, and transmit the operational parameters to the processing device in response to receiving the command.

Abstract: Analog signals are received from a sound transducer. The analog signals are converted into digitized data. A determination is made as to whether voice activity exists within the digitized signal. Upon the detection of voice activity, an indication of voice activity is sent to a processing device. The indication is sent across a standard interface, and the standard interface is configured to be compatible to be coupled with a plurality of devices from potentially different manufacturers.
