Electrical Household Appliances Control using Voice Command Based on Microcontroller

Countless improvements in digital voice recognition was developed to simplify human life. In this study, a control system for electrical household appliances in the indoor area is created, which allows one to control household appliances through voice commands. Background of this study is still found problems in terms of some homeowners forget to turn off their conventional switches and this allows the use of electricity on electronic devices for too long, causing the ability of the conducting cables to decrease so that it can trigger an electrical short circuit that generates a fire. Efforts to reduce the occurrence of this can be made by always checking the electronic devices used, or by turning off electronic devices when they are not in use. Still, often there is also a factor of being lazy or forgetting to turn off electronic devices again after use. In this study, a system that able to control household electrical appliances in a room in the house is designed and built with voice recognition, which only works if the homeowner gives orders. In this proposed study, the EasyVR Commander is implemented as a sensor that can receive voice input to control electrical household appliances, which include lights, fans, and water pumps, and home security, which has doors and safety-box. The system can recognize and process several sound samples used in the test, which indicates that the independent voice recognition method for the lamp, fan, water pump, and door components and dependent voice recognition for safety features in a safety-deposit box has been successfully implemented.
