Abstract
An audibly announcing apparatus capable of announcing updated time or results of arithmetic operations in the form of audible sounds or synthesized voices, for example, a talking clock and a talking calculator is provided with power saving circuitry. A detector is provided for detecting the operating state of the apparatus where audible sounds or synthesized voices are to be outputted. The power saving circuitry prevents power from being supplied to a voice generator consumes most of power dissipated by the apparatus, when it is not desired to output audible voices. The voice generator includes a central processing unit (CPU), a program read only memory (P-ROM) and a digital-to-analog converter.
