PROBLEM TO BE SOLVED: To provide a voice synthesis technology for selecting a more suitable optimal path. SOLUTION: A combination synthesis unit addition section 5 combines synthesis units which are candidates of search, when a synthesis unit is searched, and creates a combination synthesis unit which is a new combination unit not stored in a voice database section 2, to include it in a search path. By combining synthesis units, phoneme environment matches, and a combination unit in which a basic frequency F0 gap is small is created. Thus, possibility of being used in voice synthesis becomes high. COPYRIGHT: (C)2011,JPO&INPIT
