ABSTRACT:
A voice synthesis device is provided to include: an emotion input unit obtaining an utterance mode of a voice waveform, a prosody generation unit generating a prosody, a characteristic tone selection unit selecting a characteristic tone based on the utterance mode; and a characteristic tone temporal position estimation unit (i) judging whether or not each of phonemes included in a phonologic sequence of text is to be uttered with the characteristic tone, based on the phonologic sequence, the characteristic tone, and the prosody, and (ii) deciding a phoneme, which is an utterance position where the text is uttered with the characteristic tone. The voice synthesis device also includes an element selection unit and an element connection unit generating the voice waveform based on the phonologic sequence, the prosody, and the utterance position, so that the text is uttered in the utterance mode with the characteristic tone at the determined utterance position.
