SPEECH SIGNAL PROCESSING METHOD AND APPARATUS

摘要

FIELD: physics. ^ SUBSTANCE: when realising the speech signal processing method, energy damping coefficient values are set for background noise signals corresponding to obtained background noise frames which come after a frame with erasure masking, such that the difference between energy damping coefficient values of background noise signals, corresponding to background noise frames, and energy damping coefficient values of signals corresponding to their respective preceding frames is within the threshold range. Damping of energy of background noise signals corresponding to background noise frames is controlled using energy damping coefficient values. Other versions of the invention also disclose a speech signal processing apparatus. ^ EFFECT: transfer of energy between the region of a signal with erasure masking and the region of the background noise signal is performed naturally and smoothly such that sound perception is more comfortable for a listener. ^ 16 cl, 5 dwg
