Abstract

The present invention provides a modular headset operable to support both voice communications and voice activated commands. This may involve the use of multiple voice CODECs to process voice communications and voice activated commands. The modular headset includes both a microphone and wireless earpiece. The earpiece may further include an interface, a processing circuit, a speaker, a user interface, a pairing circuit, and a registration circuit. The interface allows the earpiece to communicate with the base unit that couples the modular headset to a servicing network. This coupling to the servicing network and base unit only occurs when the headset is successfully registered to the base unit. The pairing circuit and registration circuit allow the exchange of pairing or registration information between various components. The pairing circuit allows the wireless earpiece and microphone to exchange pairing information which is then compared to determine whether or not a successful pairing can be achieved. Analog to digital converts (ADCs), which may be located within either the microphone or earpiece are operable to process the transduced voice communications in accordance with either a voice CODEC or voice recognition CODEC depending on the selected mode of operation.
