Need help for my final project- ISD chips

TheCresent, After you generate the playback keying signal just look for the EOM signal to change and then send the stop command. That is the key to operating it in the random addressing mode. Each message has an EOM bit set into its memory at the end of each recording. As far as the quality goes, the smaller the parts memory the faster the sampling time and the better the speech quality is. I chose the 60 second part for the quality as I am using it for an 2 meter amateur repeater voice mailbox and the project I designed some time ago for work which was to play back voice recordings for a voice recognition system in one of our products uased in a durability system.

however, when i play from the start... it will played till the end of the msg...
will i be able to stop the voice playback?? by using pic?? after i estimate the time of msg being played.. then i use delay??
