VOICE SYNTHESIS DEVICE

摘要

There is provided a voice synthesis device having a large degree of freedom of the voice quality and generating a high-quality synthesis voice from text data. The voice synthesis device includes: a voice synthesis DB (101a, 101z); a voice synthesis unit (103) for acquiring a text (10) and generating a voice synthesis parameter value string (11) of the voice quality A corresponding to a character contained in the text (10) from a voice synthesis DB (101a); a voice synthesis unit (103) for generating a voice synthesis parameter value string (11) of the voice quality Z corresponding to the character contained in the text (10) from a voice synthesis DB (101z); a voice morphing unit (105) for generating an intermediate voice synthesis parameter value string (13) indicating a synthesized voice of an intermediate voice between the voice quality A and the voice quality Z corresponding to the character contained in the text (10) from the voice synthesis parameter value string (11) of voice qualities A and Z; and a loudspeaker (107) for converting the generated intermediate voice synthesis parameter value string (13) into the synthesized voice and outputting it.
