Abstract
A speech information processing apparatus synthesizes speech with natural intonation by modeling time change in fundamental frequency of a predetermined unit of phoneme. When a predetermined unit of phonological series is inputted, fundamental frequencies of respective phonemes constructing the phonological series are generated based on a segment pitch pattern model. Phonemes are synthesized based on the generated fundamental frequencies of the respective phonemes.
