A simply configured speech synthesis device and the like for producing a natural synthetic speech at high speed. When data representing a message template is supplied, a voice unit editor ( 5 ) searches a voice unit database ( 7 ) for voice unit data on a voice unit whose sound matches a voice unit in the message template. Further, the voice unit editor ( 5 ) predicts the cadence of the message template and selects, one at a time, a best match of each voice unit in the message template from the voice unit data that has been retrieved, according to the cadence prediction result. For a voice unit for which no match can be selected, an acoustic processor ( 41 ) is instructed to supply waveform data representing the waveform of each unit voice. The voice unit data that is selected and the waveform data that is supplied by the acoustic processor ( 41 ) are combined to generate data representing a synthetic speech.
