Abstract
A speech synthesizer includes a data memory having a plurality of address areas, which stores a plurality of phases in the address areas and an address designating circuit designating one of the address areas based on the phase signal. Further, a speech synthesizer includes a speech synthesizing circuit generating a speech synthesizing signal corresponding to the phase, which is stored in the designated area, a digital/analog converter transforming the speech synthesizing signal to an analog signal having amplitude, and a counter setting a period of silence. Furthermore, a speech synthesizer includes a silence-input circuit being connected between the speech synthesizing circuit and the digital/analog converter, which supplies a predetermined voltage to the digital/analog converter for the period that is set by the counter.
