In recent years, Home Automation systems have seen rapid changes due to the introduction of various wireless technologies. Zigbee is targeted at applications that require low data rate, long battery life, and secure networking and has a maximum rate of 250 kbits/s, well suited for periodic or intermittent data or a single signal transmission from a sensor or input device. This paper discusses the design of a system that allows the user to interact with it via his or her voice in natural language and maps user utterances to predefined instructions, including the switching of a light or electrical appliance. The system is intended to control all lights and electrical appliances in a home or office using natural language. Having a comfortable learning curve and being hands free by design, the system intends to make home control easier and more convenient.
