HI,

I'm doing my graduation project now on smart home and as a part of my
project I've to get a voice confirmation for some orders done using
the ISD4004 and the PIC16F877 microcontroller.
I've read the data sheet, alot of application forms & searched alot
of websites for any help but I couldn't find any thing.
I tried many shemes and programs but it was of no help. finally I
wrote a programe that seems to give me some response with the IC but
not the desired one which is recording and playing back the messages.
the programe below is the one I wrote.
So could any one help me on my prject ? ? ? ? ? ? ?
