ABSTRACT:
In a wireless selective call receiver with a speech notice function, a receiving section operates based on the power from a power supply section, and receives a radio signal to determine whether an own call number is contained in the received radio signal, and stores a message signal subsequent to the call number in a memory section when it is determined that the own call number is contained in the received radio signal. A speech output section operates based on the power from the power supply section, and outputs the message signal stored in the memory section as a speech output. A voltage determining section operates based on the power from the power supply section, and performs a voltage determination of whether an output voltage of the power supply section is equal to or lower than a predetermined reference voltage, before the speech output from the speech output section. A control section operates based on the power from the power supply section. The control section allows the speech output of the speech output section when it is determined by the voltage determining section that the output voltage of the power supply section is higher than the predetermined reference voltage, and prohibits the speech output of the speech output section otherwise.
