Abstract
The present invention discloses a method for providing full-duplex audio communication utilizing a half-duplex audio circuit in an audio communication system. The method comprises the steps of: (1) configuring an idle state, a listen state, and a talk state; (2) receiving an event triggered by one of an incoming speech, an outgoing speech, and a talk request from the half-duplex audio circuit; and (3) transitioning from one of the states to any one of the states in response to the event to provide full duplex communication.
