Patent ID: 7249022

Claim:
A singing voice-synthesizing method comprising: inputting phonetic unit information representative of a phonetic unit, time information representative of a singing-starting time point, and singing length information representative of a singing length, for a singing phonetic unit including a sequence of a first phoneme and a second phoneme; generating a phonetic unit transition time length formed by a generation time length of the first phoneme and a generation time length of the second phoneme, based on the inputted phonetic unit information; generating a state transition time length corresponding to a rise portion, a note transition portion, or a fall portion of the singing phonetic unit, based on the inputted phonetic unit information and the generated phonetic unit transition time length; and generating a singing voice formed by the phonetic unit, based on the phonetic unit information, the time information, and the singing length information which have been inputted, the generating step including adding a change in at least one of pitch and amplitude to the singing voice during a time period corresponding to the generated state transition time length.
