Abstract: A phone voice receiving/playing device includes a casing, a printed circuit board, an interface connector, an interface medium chip set, a medium enhanced chip set, a medium playing device, and a voice input device. If a software program of a computer system detects an incoming call signal of a web phone, the software program controls the interface medium chip set to convert an interface serial signal and a medium signal. After the medium signal is processed by the medium enhanced chip set, the medium signal is outputted from the medium playing device. The medium signal inputted by the voice input device can be sent to the computer system by a reverse process. The phone voice receiving/playing device also has a phone receiving/transmitting interface, and the phone receiving/transmitting interface is connected to an external phone or a mobile phone for making a call.
