PROBLEM TO BE SOLVED: To provide a voice reproducing apparatus which is capable of complementing missing frames without degrading the quality of voice neither increasing computational complexity. SOLUTION: The voice reproducing apparatus includes; an overwrite buffer 6 which arranges a plurality of normal samples in time series and repeatedly overwrites latter halves of a plurality of normal frames received in time series; a detection part 11 which detects abnormality of voice data; a backward frame generation part 12 which generates a first-half backward frame having first-half complementing samples wherein normal samples of a latter half frame of a normal frame immediately before detection of the abnormality are arranged backward in time series ; a sequential frame generation part 13 which generates a latter-half sequential frame having latter-half complementing samples wherein the normal samples of the latter half frame are arranged sequentially in time series; an output part 14 which outputs the normal frame, the first-half backward frame, and the latter-half sequential frame in order.
