Implementation of communication aid using zigbee technology

In the real time application, it is important in order to process the status information that is received every minute. A modern technology used in this system LPC 2148 based ARM7 processor is used due to its high speed, more memory and data efficiency. In globalwireless communication voice frequency is measured automation systemwhich is designed using ARM7 processor, voice recognition board and RF module. In this the robot is operated by human commands, which are sensed by a speech recognizer, processed by the LPC2148 microcontroller, and sensing loads are organized according to the programmer's instructions to the microcontroller. These orders are sent from the transmitter section to the receiver section via ZigBee wireless techniques. The order from our speech is transmitted to the receiver section via ZigBee from the speech recognizer kit and the controller in this device. The ZigBee on the receiver side receives the order from the transmitter and ZigBee, and then passes it on to the controller on the receiver side, where the commands are used to control the loads. When comparing indoor and outdoor use of ZigBee communication, it is important to remember that the data rate of ZigBee communication is much higher.
