PROBLEM TO BE SOLVED: To easily obtain natural acoustic feeling of speech at the time of transforming speech by providing this device with a sine wave component infor mation generating means for generating sine wave component information, a speech generating means for generating and outputting a transformed speech signal based on the sine wave component information, etc. SOLUTION: A shift amount setting means calculates a shift amount to be set, based on the target formant, which is a formant of a target spectral shape, and the original formant. A spectral shape generating part 23 generates a deformed spectral shape by shifting the target spectral shape in the direction of the frequency axis by the shift amount to be set. A sine wave component information generating part 26 generates sine wave component information based on the frequency components contained in the sine wave components extracted from an input speech signal and the deformed spectral shape. And, a transformed speech signal is generated based on the sine wave component information and outputted. |
