PROBLEM TO BE SOLVED: To provide a speech synthesizer which generates a natural synthesized speech of high sound quality, using elementary speech units of high quality. SOLUTION: An element speech unit selecting section 104b selects a plurality of element speech units for each synthesis unit out of elementary speech units stored in an element speech unit storage section 104a based upon distortion of a synthesized speech generated by connecting those elementary speech units. A representative element speech unit selection section 104c selects one representative element speech unit for each synthesis unit out of a plurality of elementary speech units, selected by synthesis units by the element speech unit selection section 104b, based on the distances between those elementary speech units. An element speech unit deformation/connection section 104d deforms and connects the representative element speech units selected by the synthesis units by the representative element speech unit selection section 104c to generate a synthesized speech.
