PROBLEM TO BE SOLVED: To provide a device for pitch pattern formation capable of forming a stable pitch pattern with high naturalness. SOLUTION: A pattern section section 10 selects a plurality of pitch patterns from a pitch pattern storage section 16 in prosody units, based upon language attribute information and phoneme duration length obtained from an input text. A pattern merging section 11 generates a new pitch pattern from the plurality of pitch patterns selected, based upon the language attribute information, a pattern expansion section 12 expands or contracts the pattern along the time base in accordance with the phoneme duration length, and an offset control section 14 moves it in parallel along the frequency base in accordance with an offset value 104 estimated by an offset estimation section 13. A pattern connection section 15 connects pitch patterns generated in prosody control units and outputs a sentence pitch pattern. COPYRIGHT: (C)2007,JPO&INPIT
