A speakerphone and a control method thereof are provided to minimize average current consumption of the speakerphone, by controlling an audio amplifier of the speakerphone of a mobile communication terminal dynamically according to voice activity corresponding to a voice activity factor included in a voice signal. An audio mode control part(105) converts a call mode into a speakerphone mode or a conventional call mode according to user request. A voice receiving part(101) converts voice of a caller into a voice signal. A voice compression codec part(104) receives an external voice signal, and extracts a voice activity factor of the external voice signal when the call mode is the speakerphone mode, and generates a control signal based on the extracted voice activity factor. An audio amplifier(102) amplifies the external voice signal selectively according to the control signal. A voice output part(103) outputs the external voice signal. |
