%% Add voicebox and MSR Identity toolkits to path
% Voicebox toolkit is needed for: Voice Activity Detection
% MSR Identity toolkit is needed for Extracting MFCC and LPC Features
% Download MSR Identity toolkit from: https://www.microsoft.com/en-us/download/confirmation.aspx?id=52279
% Download Voicebox toolkit from: http://www.ee.ic.ac.uk/hp/staff/dmb/voicebox/voicebox.html
% Place both the toolkits in 'utils' directory
