Automation is a trending topic in 21st century making an important role in our daily lives. Automation reduces the human labor, time, effort and some human errors. The key objective of our project is to design a system for physically handicapped persons to control and operate home appliances and their own wheel chair by their own voice. Both these qualities are present in our project which has the capability to replace existing technologies. the design of the low cost voice recognition based home automation system for the physically challenged people suffering from quadriplegia or paraplegia (who cannot move their limbs but can speak and listen) to control the various home appliances just by his/her voice commands according to their need and comfort. We also implemented a messaging concept. In this whenever the patient or the person needs a help, if he/she pronounce as help a message will be sent to their respective represented family member. The resultant system can provide a great assistance to the physically handicapped people without any need of third person.

INTRODUCTION The home automation systems are getting more popularity day to day due to their ease of use and wide operational capabilities and more applications. This Integrating voice recognition technology for home automation systems for paralyzed people can make the system more user friendly and easy to operate and control. Some require home automation system to satisfy their needs and comfort while for physically challenged people it can provide great assistance for the patients. There are several researches and developments on the home automation systems. The voice recognition based home automation system for paralyzed people uses the speech recognition module to recognize the voice commands. The RF trans-receiver is used to send these commands to the controller to control the various electrical devices and robotic wheel chair. Using of the computer makes this system more expensive and difficult to handle it. Intelligent home navigation system for disabled person uses voice recognition module v3 for the speech recognition process. An Arduino controller, a wheel chair and a navigation module. The Arduino receives the command from the voice recognition module and move the wheel chair accordingly thus eliminating the need of any third person’s assistance. This proposed a home automation system uses the voice recognition module v3 for the voice recognition function, a microcontroller and relay ABSTRACT International Journal for Modern Trends in Science and Technology Volume: 03, Special Issue No: 02, March 2017 ISSN: 2455-3778 http://www.ijmtst.com
