Recently
many police departments have become enamored with the latest gadget for
detecting lies: voice
stress analyzers. They’re
cheap, convenient, and have a high-tech look about them.
There are at least three manufacturers of these machines, but none of
them can claim to have any research supporting their use.
Instead they have relied on selective personal testimonials on how they
can be used to obtain confessions, while the routine failure of the device as a
lie detector is overlooked. Are
confessions the same as validity? Hardly.
For years cops used to get confessions from suspects with all kinds of
lie detector ruses, like wiring a naïve suspect to a photocopier, or using the
old Motorola radio in their squad cars that could change a red light to green
when the mike button was pressed. And,
a phony ploy works only so long before people catch on.
Just how accurate are voice stress analyzers?
Let’s set aside for the moment what their salesmen have to say, and
look at what the scientists have reported.

Warning to the Public |
|
| Have you lost a job opportunity with a law enforcement agency because you wrongly failed a voice stress analyzer test? You may have a legal remedy. Most large police agencies are governed by state or municipal civil service rules or laws, which make them also subject to the US government’s Equal Employment Opportunity Commission rule 29 CFR 1607, the Uniform Guidelines on Employee Selection Procedures (July 1, 1998). According to the EEOC, all employee selection tools must meet minimum standards, including validation. It is simply a matter of law that departments must use validated tools for hiring, such as the MMPI, CPI, polygraph, urinalysis, intelligence tests or others that have withstood independent scientific investigation. They are specifically prohibited from using unvalidated methods. The voice analyzer technology falls into the unvalidated category. If you took a voice stress to get a law enforcement job, it is a violation of your rights under these EEOC provisions. Contact your attorney for more advice. | |
