PROBLEM TO BE SOLVED: To provide a system and a method for speech synthesis using a smoothing filter.;SOLUTION: In the speech synthesis system for predicting a discontinuity between the sample phonemes to be used for synthesis by learning and controlling a discontinuous distortion between the phonemes of a speech synthesized by using a smoothing technology provided with a discontinuous distortion processing part for performing control so that the discontinuity between the pnonemes of a speech synthesized corresponding to a degree of such a predicted discontinuity can be suitably smoothed, a smoothing filter 30 is configured to determine a filter coefficient α to be appropriately changed corresponding to a ratio of the degree of discontinuity predicted by a discontinuity predicting part 56 and a degree of a real discontinuity measured by a discontinuity measuring part 52 in a filter coefficient determining part 40 and to perform smoothing so that the degree of discontinuity of the speech synthesized by such a filter coefficient α can follow the degree of the discontinuity predicted by the discontinuity predicting part 56.;COPYRIGHT: (C)2003,JPO
