voice over sockets

i am trying to send voice packets over network
i am using winsock APIs for nw communication and low level wave form APIs for voice
althoug the voice buffers are successfully sent through the sockets, but while receiving first of all the computer becomes extremely slow and secondly the voice is not heard at the receiving
if any body can help, in a simple way
