A physically challenged person is defined as a person who has a locomotor disability and neurological origin that constitutes a restriction in one or more of daily living activities such as using home appliances. Hence this system provides a voice which is understandable by both disabled people as well as normal people. The people with disabilities are mostly struggled to use home appliances, they always needs someone to help out. This system will allow the person to use the home appliances such as fan, light and etc., with the help of voice recognition system. People who are physically challenged struggle every day in performing their actions. This idea presents new system for control of household appliances using voice module, control of their wheelchair and an panic switch in case of emergency and helps in guiding the physically challenged people to run their day to day life with the help of hand held devices. They can turn on and off the household appliances with the use of the voice module. They can also control their wheelchair with the help of switches provided for the wheelchair motion. The system is also provided with the panic switch for emergency alert. Key Words: Voice Recognition, Arduino IDE, Locomotor, Dc Motor, Motor Driver 1. INTRODUCTION The home computerization systems are gaining popularity day by day due to their ease of use and extensive action capabilities. Incorporating voice recognition expertise to home automation systems make the system more users responsive and easy to function. Some require home automation system to satisfy their needs and comfort while for physically challenged people it can provide great assistance. There are several researches and developments on the home automation systems. The voice recognition based home automation system for paralysed people uses the speech recognition module to recognize the voice commands. This proposed a home automation system uses the voice recognition module v3 for the voice recognition function, a microcontroller and relay. 1.1 LITERATURE REVIEW There have been several researches and developments on the home automation systems. The voice recognition based home automation system [1] uses the Microsoft speech API running on PC to recognize the voice commands. The RF transreceiver is used to send these commands to the controller to control the various electrical devices. The use of computer makes this system more expensive and difficult to handle. Intelligent home navigation system for disabled and elderly person [2] proposed a system which uses voice recognition module SR-07 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. The voice recognition based home automation system [3] uses Lab VIEW to perform speech recognition and Zigbee module with a controller is used to control the devices wirelessly. The Limitation of the system [1] [3] is the use of the computer which makes system more expensive. [5] Proposed a home automation system for elderly and physically challenged people which can control the home appliances by two methods by voice commands or by using mobile as remote controller. The voice recognition is done by the android application and thus given to the controller to control the devices. The home automation system [6] proposed two ways to control home appliances that are by using timer or by using the voice commands. The software environment is developed on Virtual Basics 6.0 on PC and devices are controlled using PC parallel ports. [7] Proposed a Bluetooth based home automation system which comprises of a remote controller interfaced with microcontroller which is additionally interfaced with the Bluetooth module to provide wireless control of the appliances. When key on the remote controller is pressed the controller sends the command via Bluetooth module to the receiver and corresponding action on the receiver side is taken.
