1. A voice signal processing apparatus, comprising:
a processing unit, lowering a frequency of a sampling voice signal to generate a frequency-lowered signal including a sequence of frequency-lowered signal windows, wherein each of the frequency-lowered signal windows does not include an overlapping data section, and the processing unit further divides each of the frequency-lowered signal windows into a first sub signal window and a second sub signal window, performs a fade-in process and a fade-out process on the first sub signal window and the second sub signal window respectively, overlaps the first sub signal window and the second sub signal window adjacent to each other and belonging to the different frequency-lowered voice signal windows in order to generate an overlapping voice signal, and combines the sampling voice signal and the overlapping voice signal to generate an output signal. |
