MULTI-PURPOSE VOICE ACTIVATED CONTROLLER

This project, a multipurpose voice-activated controller is a device that can be activated
using human voice instead of the conventional switch. Devices which can be voice
activated brings more convenience and allows a certain safety measure as it allows user
to not be in physical contact with the appliance. This project is divided mainly into the
hardware and software part. The software part is implemented first. Software part
includes MATLAB. MATLAB programming receives and processes audio command
from microphone and is used to implement the speech recognition and sending output to
trigger the microcontroller. PCB development involves use of EAGLE software. The hardware part involves the HM2007 IC utilized in the speech recognition circuits as well as an interfacing circuit to control the external appliances. This project will be implemented on table lamp and doorbell.
