Abstract
Disclosed is a speech receiving apparatus. A low-band PLC module and a synthesis filter reconstructs a low-band speech signal of a lost frame from a previous good frame. A high-band PLC module reconstructs a high-band speech signal of the lost frame from the previous good frame. A transforming part transforms the low-band speech signal into a frequency range. A bandwidth extending part generates at least an extended MDCT coefficient as information for the high-band speech signal from the low-band speech signal transformed by the transforming part. A smoothing part smoothes the extended MDCT coefficient. An inverse transforming part inversely transforms the extended MDCT coefficient smoothed by the smoothing part to a time domain. A synthesizing part synthesizes the low-band speech signal, and the high-band speech signal which is inverse-transformed by the inverse transforming part and reconstructed, to output a wideband speech signal.
