PURPOSE:To reduce the amount of packet voice to be scrapped, and to heighten the quality of reproducing sound, by reproducing a packet voice until the next reproduction timing when the packet voice is not stored in a buffer memory at the time of generating a packet reproduction timing signal, and it is stored at the time of generating a following sub-timing signal. CONSTITUTION:When an initial packet voice P1 is sent from a transmission side through a transmission line 1, and it is stored in a buffer memory 3, a packet processing part 4 transfers it to a timing signal generation part 7, and extracts sound data from the packet voice P1 by a signal sent from the generation part 7 after a queuing time T, and sends it to a demodulator 5. Next, at the time of issuing packet reproducing timing signals t1, t2, ... from the timing generation part 7, the packet voice to be processed is reproduced if it is stored in the buffer memory 3, and even if the packet voice to be processed is not stored, the packet voice is reproduced in double speed if the packet voice to be processed is stored in the buffer memory 3 at the time of issuing following sub-timing signals S1, S2, ....
