Abstract  Abstract

According to an embodiment of the present invention, the speech processing method includes determining an unvoiced / voiced speech parameter reflecting the characteristics of unvoiced / voiced speech of a current frame of a speech signal comprising a plurality of frames. A smoothed unvoicing / voicing parameter is determined to include information of the unvoiced / voiced parameter of the frame before the current frame of the speech signal. The difference between the unvoiced / voiced sound parameter and the smoothed unvoiced / voiced sound parameter is calculated. The speech processing method further includes generating an unvoiced / voiced sound decision point for determining whether the current frame includes unvoiced speech or voiced speech using the calculated difference as a determination parameter.
