Claim Text:
1. A voice processing apparatus comprising one or more of processors configured to: adjust, in the time domain, a fundamental frequency of a first voice signal corresponding to a voice having target voice characteristics to a fundamental frequency of a second voice signal corresponding to a voice having initial voice characteristics different from the target voice characteristics; and sequentially generate a processed spectrum based on a spectrum of the first voice signal and a spectrum of the second voice signal by: dividing the spectrum of the first voice signal into a plurality of harmonic band components after the fundamental frequency of the first voice signal has been adjusted to the fundamental frequency of the second voice signal; allocating each harmonic band component obtained by dividing the spectrum of the first voice signal to each harmonic frequency associated with the fundamental frequency of the second voice signal; and adjusting an envelope and phase of each harmonic band component according to an envelope and phase of the spectrum of the second voice signal.
