Controlling appliances is a main part in automation. In future, voice recognition technique will be the method for controlling appliances, computers and robots. There is a huge demand waiting for this technology to come into effect. Voice recognition is a standalone and very less expensive technique that may be used to control electrical appliances. The whole kit can be divided into two parts. Part one includes hardware and second includes software. In hardware we are using the USB to UART interface and controller and interface for the device control. We will control 4 devices as prototype.
It does can be further extended if we code for more commands. For our simplicity we will control here only 4 devices which are being controlled directly by the controller on basis of voice commands. In software section we shall use visual basic (require VB 6.0) to interact with the computer and USB port for communication.
The different appliances can be controlled very easily by voice. It can be used in military application where soldiers are given command so it can also be used there. It can be further implemented into robots which operate on voice.
