PURPOSE: To obtain a packet communication system with high quality even if the delay of a voice packet is varied, by adding sound starting information to the voice packet to process the voice packet.
CONSTITUTION: A start information generator SPG adds starting information to a packet. Receiving a control signal S119 in each voice data block, the SPG supervises a control signal S118 outputted from a voice detecting circuit VDET to detect a voice data block corresponding to voice starting out of respective voice data blocks. The starting informatiin dlt is supplied to a voice packet transmitting circuit PVT through a data line 115 and used for the assembling of the starting information field of the voice packet. In a voice data block discriminated as voice, a transmission control signal tpt is supplied to a packet transmitting circuit PUT and the corresponding voice data vdt, sequential- number sqt and starting information dlt are supplied to the PVT and assembled as a voice packet to be sent to a data line 111.
