The present invention is to provide a voice device, which comprises a sensor unit adapted to generate an idle signal in response to an idle state of the voice device, and a control circuit capable of determining that the voice device is idle after receiving the idle signal and issuing an alert message through a second sound transmission unit for alerting user of any incoming call based on the idle state of the voice device. The control circuit is also capable of determining that the voice device is in use after receiving the use signal, enables the sensor unit generates a use signal, and then commands a first sound transmission unit to play voice. By utilizing this voice device, it is possible of solving the problem of playing an alert message in an excessively reduced volume as experienced by the conventional voice device.
