A voice synthesis device for generating synthetic voice having great freedom in voice quality and good sound quality from text data is provided. The voice synthesis device is provided with: voice synthesis DBs (110a and 101z); a voice synthesis unit (103) for acquiring a text (10) and generating a voice synthesis parameter value sequence (11) of voice quality A which corresponds to a character that is included in the text (10) from the voice synthesis DB (101a); a voice synthesis unit (103) generating a voice synthesis parameter value sequence (11) of voice quality Z which corresponds to a character that is included in the text (10) from the voice synthesis DB (101z); a voice morphing unit (105) for generating a intermediate voice synthesis parameter value sequence (13) for indicating synthetic voice of intermediate voice quality between voice quality A and voice quality Z which corresponds to a character that is included in the text (10) from the voice synthesis parameter value sequence (11) of voice quality A and voice quality Z; and a speaker (107) for converting the generated intermediate voice synthesis parameter value sequence (13) to the synthetic voice and outputting the resulting synthetic voice.
