Are the lie detector tests on television real?
In some cases, yes and in other cases, no. Because the polygraph test takes 2-3 hours to perform, it’s usually done before a show. Then, while on camera, the examiner will perform a mock polygraph test. Some television shows are now utilizing voice stress analysis, but they’re mostly for entertainment. And, as such, they don’t use the high end voice stress analysis instrumentation that is used for serious matters, such as your situation or those done by law enforcement or government agencies. The voice stress analysis technology (DVSA) is NOT a toy nor is it used for personal entertainment purposes. There are toys and low end equipment on the market that use TVSA or layered voice technologies that are meant for fun.
