To provide a voice synthesizer for outputting voice suppressive in occurrence of distortion.
A waveform generating device 200 included in the voice synthesizer is provided with: an energy changing section 210 for changing energy information Ep to energy information corresponding to volume indication information Ev; an energy correction section 220 for correcting energy information E based on a correction data prepared beforehand; a waveform decoding section 230 for decoding and outputting a waveform of a time unit defined beforehand, from waveform information for each period defined beforehand; and an amplifier section 240 for amplifying and outputting a waveform S[i] generated by decoding, based on energy information f(E) after correction.
