for storing the voice you can use APR9600, there are projects discusses in this forum about interfacing the APR9600 to controller...

i think you can interface any port(89c52) directly to /M1 to /M8 of apr9600
you can keep port value high when there is no message play
when you want to play message 1 then keep example p2.0 clr for one sec then again to set
then your message1 will play .thanks

use vs1011e breakout board from Sparkfun.
see this thread. Code is all there for 89S52.

Study APR9600's DataSheet for more detail as everything is discussed in very detail for interfacing different modules with it.

Your Topic is itself wrong. AT89C52 is not an AVR Controller, it is 8051 core.
