VOICE SYNTHESIZER AND NATURAL LANGUAGE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a voice synthesizer which can read a text of written words aloud with a rhythm close to that of spoken words by replacing the text with expression of the spoken words and read the text aloud naturally with the spoken words. SOLUTION: A text conversion part 140 converts a part in an input text which corresponds to a pattern of written words of a text conversion rule registered in a text conversion rule table 130 into spoken words specified by the rule. A rhythm information control part 190 gives rhythm information which is specially prepared for the spoken words to the part converted into the spoken words and generates a rhythm other than the converted part according to the rule by using a parameter so set as to naturally connect with the converted part.
