The present invention provides an apparatus and a method for transmitting and receiving a voice packet, capable of adjusting a transmission bandwidth or time of the voice packet by using feedback information. According to one embodiment of the present invention, the apparatus comprises: an input unit inputting a first voice data received from a user; a segmenting unit segmenting the first voice data into each predetermined unit; a first processing unit dividing the segmented first voice data into each pitch unit, detecting an overlapped pitch similar to a neighboring pitch included in the first voice data, and removing the overlapped pitch to reduce the length of the first voice data; a second processing unit coding the first voice data from which the overlapped pitch is removed to generate a first voice packet; a third processing unit encrypting the first voice packet by using a security key; and a communication unit transmitting the encrypted first voice packet to a voice packet transmitting and receiving apparatus of a receiver side. |
