Abstract  Abstract

According to one embodiment of the present invention, a speech processing method includes determining unvoiced / voiced sound parameters that reflect 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 sound parameter of the frame before the current frame of the speech signal. The difference between the unvoiced / voiced parameter and the smoothed unvoiced / voiced parameter is calculated. The speech processing method further comprises generating an unvoiced / voiced sound determination point for determining whether the current frame includes voiced speech or includes voiced speech using the calculated difference as a determination parameter.
