A voice decoding device for reproducing the sound information which is encoded in a predetermined frame unit and packet-transmitted is provided. An interframe-predicting unit continuously predicts a series of data over plural frames. A control unit always monitors whether the absence of a packet occurs or not. When the absence of a packet is detected, a selector is switched, and the decoding processing of the voice signal is performed using a series of predicted data over plural frames obtained at the interframe-predicting unit instead of a series of received data used in the usual voice decoding processing.
