Document Type and Number:

Japanese Patent JP4787769

Kind Code:

B2

Abstract:

To generate an F0 value time series inexpensively in accordance with various tones at low cost.

A text in which a boundary position is determined for every accent phrase, and starting time and ending time are determined for each multiple accent types and moras, is input (3, S2). By using a rhythm event table, a plurality of rhythm events are related to an indicated position of the accent phrase according to the accent type (12, S8). By using a rhythm event table classified by tones, a rhythm event classified by tones, which corresponds to generation condition of the accent phrase is added (13, S10). A rhythm event parameter is created for each rhythm event from a rhythm event parameter data base (22, S12), and a delta function is created for each rhythm event from a creation function table (16, S16). An initial F0 value is calculated for each accent phrase (18, S18), and the F0 value time series is created for each accent phrase from the delta function and the initial F0 value (20, S20).
