PROBLEM TO BE SOLVED: To generate such a pitch pattern hardly causing unnatural synthesized sound by generating information on the modulation of the pitch of a unit for every unit when a mora or syllable is regarded as the unit and generating the pitch pattern by using the information on the modulation of pitches of those units. SOLUTION: A text analysis part 2 takes a text analysis of an inputted text such as a morpheme analysis to divide the text into analytic units such as morphemes and gives various information on characteristic accent types, parts of speech, etc., by readings and its analytic units. A unit pitch information generation part 3 generates unit text information on units from various information on analytic units when moras of a synthesized sound are regarded as the units and generates information on the modulation of pitches of the units for every unit. A pitch pattern generation part 4 generates a pitch pattern based on the information on the modulation of unit pitches and various information of the analysis units. |
