摘要： Some of the repetitively generated impulse response signals are inverted for their polarities, and particular harmonics only are erased/attenuated. The rate of generating the impulse response signals remains constant or changes relative to the pitch, and the tones of the fixed formant type or the tones of the moving formant type are selected. Both ends of the impulse response signals are cut off, whereby the impulse response signals are superposed one upon the other in a decreased amount, and the amount of operation decreases. A plurality of impulse response signals are synthesized to generate impulse response signals different from the impulse response signals of before being synthesized. The rate of generating the impulse response signals changes not in proportion to the pitch, and tones of the moving formant type or generated changing more mildly than a change in the pitch.
