Lionel prefers working with VSA Lie detection rather than Polygraph Lie Detection. (VSA – Voice Stress Analysis)
Accuracy and deterrent: On average it is found that voice stress analyses tests (lie detection) are 97% accurate.
It is also found that the mere fact that people believe or understand from VSA (lie detection) testing that the software will indicate or detect their lies, can also be a deterrent not to lie during interrogation.

What Is VSA?
“VSA software programs are designed to measure changes in voice patterns caused by the stress, or the physical effort, of trying to hide deceptive responses. VSA programs interpret changes in vocal patterns and indicate on a graph whether the subject is being "deceptive" or "truthful."
