Smart Phone as a Controlling Device for Smart Home using Speech Recognition

摘要

The smart homes are now becoming the requirement of the modern world. The days are now becoming thing of past when Smart Homes were only limited to sci-fi movies, it has gained much achievements and popularity over the last few decades. Home automation has given an entirely new meaning to living as compared to past days. Earlier all our home appliances such as television, AC, lights, fans etc. were operated by a specific remote controller for each appliance. There comes a problem too as handling all those remotes is hectic sometimes especially for the older and the disabled one. In this paper, an overview of a solution to this problem is discussed that all such devices can also be operated by only a single remote controller rather than one remote controller per device. This universal controller can be easily implemented in a cost-effective way by just using any existing smartphone and an Arduino microcontroller via Bluetooth transmission. Thus, smartphone-based controlling devices eliminate the need for carrying many different remote controllers. In addition, controlling devices by speech avoids looking for various buttons/options while operating the devices. The study aims at developing a signal based smart home network for controlling the electronic appliances by the voice recognition system.
