The word “Embedded” itself gives the meaning as the combination of different components are mounted in to a single device, which is also called a system on chip. With the help of VLSI technology it became possible to develop high speed, with low cost, and power efficient and small in size type Integrated Chips. The Micro controller, which is used for this purpose is called IBP (Itty Bitty Processor) or embedded processor due to the fact of its instruction execution speed. The multi task handling system that introduces time delay, which is not at all desirable in any application, in such case, the micro controllers which can play a key role as an embedded system design is more suitable one. Here, we design a generalized embedded system application “voice controlled home appliances” is the evidence for the efficient automation, and is constructed around the microcontroller and VRC is (Voice/speech Recognizer kit). In this the home appliances are controlled according the commands given by the human and the commands are recognized by the speech recognizer and the commands are processed by the micro controller and loads are controlled according to the instructions given to the micro controller by the programmer. These commands are transmitted to the receiver from transmitter through the zigbee wireless communication Zigbee works as a transreceiver here; the commands of our speech are transmitted to the receiver through zigbee from the speech recognizer kit and the controller. The receiver side zigbee will receive the commands from the transmitter and zigbee and then to the controller and loads are operated through these commands.
