Abstract: A method for speech signal processing is provided. Energy attenuation gain values are set for background noise signals corresponding to obtained background noise frames subsequent to an erasure concealment frame, so that differences between the energy attenuation gain values of the background noise signals corresponding to the background noise frames and the energy attenuation gain values of signals corresponding to their respective previous frames are within a threshold range. Energy attenuation of the background noise signals corresponding to the background noise frames is controlled by using the energy attenuation gain values. An apparatus for speech signal processing is also provided in embodiments of the present invention. By using the embodiments of the present invention, the energy transition between the area of erasure concealment signal and the area of background noise signal may be made natural and smooth, so as to improve the audio comfortable sensation of the listener.
