    • In a voice processing apparatus, a processor is configured to adjust, 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. The processor is further configured to 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; allocating each harmonic band component 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 the spectrum of the second voice signal.
    • 在语音处理装置中,处理器被配置为将与具有目标语音特性的语音相对应的第一语音信号的基频调整为对应于具有与目标不同的初始语音特征的语音的第二语音信号的基频 声音特征。 处理器还被配置为通过以下方式顺序地生成基于第一语音信号的频谱和第二语音信号的频谱的处理频谱:将基本频率的第一语音信号的频谱划分为多个谐波频带分量 第一个语音信号已被调整; 将第一语音信号的每个谐波频带分量分配给与第二语音信号的基频相关联的每个谐波频率; 以及根据第二语音信号的频谱调整每个谐波频带分量的包络和相位。
