Abstract
An apparatus and method for controlling a speaker's volume of a push-to-talk (PTT) phone avoid an undesirably loud volume sound from the speaker that may be caused due to inadvertence of the user during a PTT call mode. While in a PTT call mode, physical contact between the user and a contact sensing unit, provided at a PTT button or at an earpiece, is sensed. The speaker volume is automatically adjusted according to how the user is holding the phone, as determined by the contact sensing unit. Thus, the emanation of undesirably loud sounds from a loud speaker of the phone (e.g. as occurs during a PTT session) can be prevented when it is determined that the user has the earpiece adjacent to their ear (e.g. as occurs during a normal mobile telephone conversation).
