<P>PROBLEM TO BE SOLVED: To provide a speech synthesizing method, and a device and a computer program therefor that can synthesize an optimum speech according to a situation and synthesize a speech of high quality, and an information storage medium stored with the same. <P>SOLUTION: Control information for speech synthesis including pieces of information specifying at least one of a phoneme series, a fundamental frequency value a goal of speech synthesis, a continuous time length, a data base in use, and a signal processing method, and input information 100 including character data as an object of speech synthesis are obtained to select an elementary speech unit used for the synthesis from a database part 202 and evaluate the quality of the selected elementary speech unit; when the evaluation result does not satisfy a reference value, selection processing for an elementary speech unit is carried out repeatedly according to the control information included in the input information 100. Consequently, an elementary speech unit whose evaluation result reaches the reference value is selected and used to synthesize a speech. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
