The project develops the switching of devices through voice commands. Therefore, the focus is on the change of device and GSM modem control to send SMS in case of emergency, all controlled by voice commands. To be specific, there are three main objectives in this project. First, to design and build a voice activated device switching system to help people with physical disabilities and the elderly. Second, to control electrical devices such as light, fan, etc. with the help of voice recognition system. Finally, to provide a communication mechanism between the user and the predefined number via SMS messages via GSM modem in case of emergencies. The method used during system development involves the use of Visual Basic 6.0 (V.B.6.0) and Microsoft Speech API to detect commands, RS232 serial port to receive and transmit data from a computer and PIC16F877A to control relays. As a result, there are four coding sets involved, ie C coding, V.B.6.0 coding to create GUI, GSM coding and HTML in V.B. 6.0. Although many systems have been developed that use voice recognition such as voice-enabled wheelchairs, home-enabled voice charges and many more, they do not provide monitoring capability. In this project, the user has the ability to monitor the loads and the security system through HTML from anywhere, using any device, as long as they are connected to the same network.
