In embedded or electronics projects there is need of voice guidance or the people making project in DTMF needs IVR system to give voice reply at the output.
So most of the people prefer IPOD, MP3 player, or SDCARD Module. All the things are costly and difficult in connecting to the system. Sometimes even there is problem in sound generating some kind of noise.

The systematic or typical way is to use specialized voice circuitry which can be operated by any microcontroller and the message can be played by the microcontroller logic controlling the chip. This can be easily done using IC APR33A. This is new IC in the market. It can store recording upto 11 Minutes. And it can be operated upto message mode of 1/2/4/8, depending on the requirement of user.
