To provide a voice decoding device which can reduce the influence of a decoding error on a decoding process after recovery from a frame error if a frame error occurs during transmission as for a voice decoding device which receives encoded information generated by linear prediction analysis and outputs a synthesized voice.
The voice decoding device receives encoded information generated by linear prediction analysis and outputs the synthesized voice by using the encoded information and information held in an internal memory wherein voice information generated in the past is fed back and held, and is equipped with an error recovering means which updates the contents held in the internal memory by using the information held in the internal memory at least right after a frame error as to a frame recovered to a state wherein the encoded information can be received normally from the state of the frame error wherein the encoded information can not be received normally.
