PROBLEM TO BE SOLVED: To obtain a voice decoding device which can suppress deterioration in voice quality even in continuous voice transmission wherein a soundless section appears at low frequency. SOLUTION: When the amount of voice encoded data stored in a fluctuation absorption buffer 12 becomes less than a lower-limit data amount, a speech signal stored in a speech signal storage buffer 15 is interpolated and when the amount of speech encoded data stored in the buffer 12 becomes larger than an upper-limit data amount, on the other hand, the speech signal stored in the storage buffer 15 is thinned out.
