Abstract
A processing unit of a voice processing apparatus first generates a target voice signal 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 the target voice signal after pitch is adjusted. Second, the processing unit reallocates, along a frequency axis, the spectrum of the target voice characteristics by having the spectrum correspond to each of the fundamental frequencies of the initial voice signal. The processing unit then generates a converted spectrum by adjusting component values of the spectrum of the target voice characteristics, which spectrum has been reallocated, so as to correspond to the component values of the spectrum of the initial voice signal, and by adapting the component values of the spectrum of the initial voice signal to specific frequency bands of the spectrum of the target voice characteristics, with each specific frequency band including one of the harmonic frequencies corresponding to the fundamental frequency of the initial voice signal.
