摘要：A processing unit of a voice processing apparatus first generates a target voicesignal in a time domain by adjusting a fundamental frequency of a target voice signal to a
fundamental frequency of an initial voice signal, so as to generate a spectrum of thetarget voice signal after pitch is adjusted. Second, the processing unit reallocates, along afrequency axis, the spectrum of the target voice characteristics by having the spectrumcorrespond to each of the fundamental frequencies of the initial voice signal. Theprocessing unit then generates a converted spectrum by adjusting component values ofthe spectrum of the target voice characteristics, which spectrum has been reallocated, soas to correspond to the component values of the spectrum of the initial voice signal, andby adapting the component values of the spectrum of the initial voice signal to specificfrequency bands of the spectrum of the target voice characteristics, with each specificfrequency band including one of the harmonic frequencies corresponding to thefundamental frequency of the initial voice signal.
