Abstract  Abstract

The embodiment of the invention discloses a method and device for processing voice frequency signals. In one type of the embodiment, the method for processing the voice frequency signals comprises the steps that an initial high-frequency band signal corresponding to a current frame voice frequency signal is acquired when bandwidth switching appears in the voice frequency signals; time-domain overall gain parameters of the initial high-frequency band signal are acquired; weighting processing is carried out to an energy ratio and the time-domain overall gain parameters and obtained weighting values are taken as predicted overall gain parameters, wherein the energy ratio is a ratio between energy of a historical frame high-frequency band time-domain signal and energy of the current frame initial high-frequency band signal; the initial high-frequency band signal is amended by the predicted overall gain parameters, and an amended high-frequency band time-domain signal is acquired; and a current frame narrow-frequency band time-domain signal and the amended high-frequency band time-domain signal are compounded and then output.
