PROBLEM TO BE SOLVED: To solve problems wherein when a fundamental frequency pattern is generated, a fluctuation in fundamental frequency in a mora can not precisely be determined, and a rhythm represented by an accent becomes unnatural owing to distortion generation on a real-time axis. SOLUTION: Provided are: a phoneme time length standardized fundamental frequency database 351 which stores the number of the moras of an accent phrase, a rise reference point of an (i)th mora as the peak of a fundamental frequency pattern, etc., in the form of positions relative to the time length of a phoneme of a specified mora; a fundamental frequency pattern deformation database 350 which stores peaks of an accent phrase by positions in phrases of the accent phrase and the quantity of deformation in fundamental frequency at the ending; a time length setting part 40 which sets a time length of each phoneme by referring to a phoneme time length database 30 according to phoneme information etc., outputted from a character string analysis part 20; a generation part 60 which generates a fundamental frequency pattern by referring to the above-mentioned database 351 according to the above-mentioned outputted phoneme information and the time length of a phoneme set by the time length setting part 40; and others.
