It is possible to provide a speech synthesis device, speech synthesis method, and speech synthesis program which can improve a speech quality and reduce a calculation amount with a preferable balance between them. The speech synthesis device includes: a sub-score calculation unit (60/65) which calculates a segment selection sub-score for selecting an optimal segment; and a candidate narrowing unit (70/73) for narrowing the candidates according to the number of the candidate segments and the segment selection sub score. The speech synthesis device performs candidate narrowing by the sub score calculation unit (60/65) and the candidate narrowing unit (70/73) in the candidate selection process when generating a synthesized speech from an input text.
