deception detection systems in a highly relevant and highly controlled
manner. The two systems were the National Institute for Truth
Verification’s (NITV) Computer Voice Stress Analyzer (CVSA) and
Nemesysco’s Layered Voice Analysis (LVA), distributed in the United
States by V. The devices were tested in a double-blind study rather than one
that included both an operator and an on-scene event involving human
subjects. It was through the use of this paradigm that the systems
themselves, apart from the operators’ abilities or use of non-system
information, could be evaluated in a thorough and impartial manner. The
project was completed as tasked and in its entirety. In the course of
completing all tasks, additional relevant research was conducted – as
were procedures which included the use of highly experienced operators
provided by the manufacturers. These several additional subprojects are
reported along with the project results to enable a larger understanding of
the sensitivity of these two devices to deception in speech. |
