Advanced Lie Detector 2.0 is out!

Announcing the 2.0 release of Advanced Lie Detector. A computerized Voice Stress Analysis Tool.



Summary:
This application performs stress classification and quantification utilizing non-linear speech features as indicated in NATO published research.

Features Include:

  • Critical Band based Teager Energy Operator autocorrelation envelope area algorithm (TEO-CB-Auto-Env).
  • Adjustable playback accuracy for faster phones.
  • Graphical Stress display of captured speech.
  • Playback analysis speed adjustment from 25% - 100%

Note: The algorithms detect stress/nervousness present when someone tells you a lie and fears being caught. If you are testing this on yourself, there is no consequence of being caught lying, therefore no stress to detect.  Therefore, it would be counter-productive to use it on yourself as a lie-detector. Perhaps using it on someone else would be a better idea.

Furthermore, before you rate my application, please be aware that this app uses research published by NATO. I make no claims as to the accuracy of the stress/lie detection capabilities of their algorithms. I have only implemented one particular algorithm (TEO-CB-Auto-Env), as I was curious if real world results would match their lab test results.
If it doesn't work for you, don't blame me... blame the researchers.

Feel free to read their
research results and come to your own conclusion. I hope you guys enjoy this application!

  1. I went to open the linked research paper and couldn't open it because the file is damaged, do you have another link?
