Voice Interfacing Automatic Moving Camera

Abstract

This thesis report aims to design and implement an automatic system which interfacing with motor by tracking the voice of the speaker. Here the total working procedure has been divided into two portions: Software and Hardware part. In order to the system operational, MATLAB software and ARDUINO microcontroller has been used for interfacing with the hardware parts. This proposed system first track down the speaker voice by using microphone and then move the camera towards the speaker. This algorithms have been used to detect the specific microphone and for the right angle movement of the stepper motor. This system can track down the microphone and as well as it can move the motor with camera towards the speaker. The speed and angel accuracy of motor depends on the delay time between motor rotation codes. The angel accuracy and sharpen the motor rotation has also been improved. Finally, it is found that shorten the delay may improve the speed and accuracy of motor rotation.
