Patent ID: 7016841

Claim:
A singing voice synthesizing apparatus comprising: a phoneme database that stores a plurality of voice fragment data formed of voice fragments each being a single phoneme or a phoneme chain of at least two concatenated phonemes, each of the plurality of voice fragment data comprising data of a deterministic component and data of a stochastic component; an input device that inputs lyrics; a readout device that reads out from said phoneme database the voice fragment data corresponding to the inputted lyrics; a duration time adjusting device that adjusts time duration of the read-out voice fragment data so as to match a desired tempo and manner of singing; an adjusting device that adjusts the deterministic component and the stochastic component of the read-out voice fragment so as to match a desired pitch, said adjusting device being configured to adjust the stochastic component by varying a low frequency region of an amplitude spectrum of the stochastic component according to the desired pitch; and a synthesizing device that synthesizes a singing sound by sequentially concatenating the voice fragment data that have been adjusted by said duration time adjusting device and said adjusting device.
