Abstract:

The proposed paper discusses about the MATLAB approach for detection of deception. The audio of the person is recorded in real time and is converted into wav format. This wav file is then loaded and run using a MATLAB code which detects whether there is deception. The dime-domain features and frequency-domain features are analyzed in order to detect variations in the recorded voice file.
