as per i know aplus ics are specially made for voice recording and playing it using pwm or ledder network. you have to attache a speaker to designated pins on it. and microphone too. it seem that this module has no interface to connect it to any micro controller. it can not send recorded data to micro controller. all you can do is trigger its record playback pins using micro controller. you can use separate rf trans receivers to communicate between uc and apr9600. but still you can send only playback commands not the entire voice file. you have to put an another micro at the end having apr9600 to receive commands, which will toggle pins according to your usage.
