PROBLEM TO BE SOLVED: To provide a speech synthesizer that selects a suitable speech segment from multiple speech segments each having a different number of phonemes.SOLUTION: A storage device 12 stores therein segment data DV of each of multiple speech segments that include two or more speech segments each having a different number of phonemes. A segment selection unit 26 selects a speech segment for each specified sound. Specifically, the segment selection unit 26 selects a speech segment that has a larger number of phonemes when two or more speech segments each having a different number of phonemes exist as candidates to be selected for a single specified sound. A speech synthesis unit 28 generates a speech signal SOUT using the segment data DV of a speech segment selected by the segment selection unit 26. |
