<p>A speech synthesis device includes a pitch pattern generation unit (104) which generates a pitch pattern by combining, based on pitch pattern target data including phonemic information formed from at least syllables, phonemes, and words, a standard pattern which approximately expresses the rough shape of the pitch pattern and an original utterance pattern which expresses the pitch pattern of a recorded speech, a unit waveform selection unit (106) which selects unit waveform data based on the generated pitch pattern and upon selection, selects original utterance unit waveform data corresponding to the original utterance pattern in a section where the original utterance pattern is used, and a speech waveform generation unit (107) which generates a synthetic speech by editing the selected unit waveform data so as to reproduce prosody represented by the generated pitch pattern.</p> |
