US Patent Office Awards Scoring Algorithm Patent to NITV's Founder, Charles Humble

In January of 2008, the US Patent Office awarded a patent for the ‘Method of Quantifying Psychological Stress Levels Using Voice Stress Pattern Samples’ to NITV’s Founder, Charles Humble.  In 1982, in break-through research conducted by Charles Humble, he was able to quantify voice stress patterns for the first time and to then determine, through a numerical process, the threshold for deception.  This and many other discoveries by Charles Humble dramatically increased the accuracy of voice stress analysis and led to over 1,700 law enforcement agencies, including most metropolitan agencies, federal agencies, and the US military, to utilize the Computer Voice Stress Analyzer.  The CVSA is the only voice stress analyzer with a patented scoring algorithm and the only voice stress analyzer widely accepted in the law enforcement/military community.

Charles Humble is to be congratulated on this accomplishment and we offer our appreciation for his long and dedicated career in truth verification.
