Abstract
A voice signal processing method processes voice signals acquired by a microphone. A voice processing device acquires first voice signals according to a first sampling frequency, and samples second voice signals from the first voice signals according to a second sampling frequency. The second voice signals are encoded to obtain a basic voice package. A voiceprint data package of each voice signal frame of the first voice signals is obtained using a curve fitting method, and a pitch data package of each voice signal frame of the first voice signals is obtained according to pitch distribution of twelve central octave keys of a standard piano. The voiceprint data package and the pitch data package are embedded into the basic audio package to generate a final voice package of the first voice signals.
