Since most people in the private sector have heard of the traditional polygraph, there really isn't a need to discuss this in great detail. However, since the voice stress analysis (also known as voice polygraph) is new to most people, we will take the time to explain it here.

The voice polygraph was developed by the U.S. Military over 50 years ago for covert operations, as a means to determine deception and gather intelligence, as well as a way to replace the traditional polygraph due to some if its flaws. This technology allowed them, as us today, to analyze ANY type of voice recording, including telephone conversations, television and radio programs or audio from cassette tapes, CDs or DVDs, as well as from MP3 or WAV files.

You may be asking yourself, "How can you determine if someone is being deceptive or not just from a voice recording?". Well, that's a great on for the answer.

The voice polygraph (voice stress analysis) test measures an involuntary reflex in the body that occurs under stress called a microtremor. This microtremor occurs at a sub-audible level, which means it's below what the human ear can hear. The microtemor is usually between 8 Hz to 12 Hz and the human ear can hear from about 20 Hz on up. This is why we have to record the entire testing process so that we can use our computerized instrumentation to analyze these changes for deception.

We DO NOT use Layered Voice Analysis, as this technology is used for entertainment purposes for those that don't take true deception detection seriously. DO NOT USE LIAR CARD IF YOU ARE SERIOUS ABOUT GETTING ACCURATE RESULTS.

The Insurance industry is probably the biggest commercial user of the voice polygraph (voice stress analysis) test technology. For example, when someone has an auto accident, they will need to explain to the insurance company what occurred. As they are telling their story over the phone, the entire conversation is being recorded and will then be later analyzed for deception. If the insurance company finds that you were lying about your story, then they won't pay the claim.
This technology has been used for many years to monitor suspicious 9-1-1 emergency phone calls. Whenever an operator feels that the person on the other end of the phone is acting out of character for someone undergoing an emergency, the tape recorded conversation is analyzed to determine whether or not additional investigation is necessary.
And, Homeland Security relies on the voice polygraph (voice stress analysis) technology to help protect our country from terrorist activities. They will tape record and analyze the terrorists' phone conversations.

The voice polygraph must be a viable solution if the U.S. Department of Homeland Security is using it to protect us.
The CIA and FBI use if for gathering intelligence among other purposes. In any situation where they can record and analyze the voice, they rely on the voice polygraph.

Many Police and Sheriff department use it for their investigations, as well as use it for their pre-employment screening of prospective policeman and law enforcement officers. Telephone wire taps from phone conversations can analyzed for deception.
Even some professional baseball teams make their players go through this process over the phone each monitor for behavioral purposes.

With more and more professional athletes in the news, team owners, managers and coaches want to be sure that their players are acting in a professional manner.

Post-convicted sex offenders have to go through this process over the phone each month as a part of their probation to make sure they're following the guidelines. They are asked questions like "Have they been within 1 mile of a public park or elementary school?"

Now, many airports are starting to use this technology to screen travelers.

Additionally, the voice polygraph (voice stress analysis) test is used in criminal and civil cases. Many courts throughout the country allow these test results to be admissable. Be sure you check with your attorney to confirm if the court that is handling your case allows these tests as admissable forms of evidence.

You may be asking yourself, "Can this really work for my situation?" The answer is "Absolutely!" If it is used and relied upon by the CIA, FBI, NSA, Homeland Security, the military, the Insurance industry and numerous other law enforcement and government agencies, as well as used in criminal and civil cases, then it's definitely good enough for your situation. Don't let the fact that it's new to you stop you from using this widely used and heavily relied upon technology.

The only limitation to this technology is if the person taking the test uses Skype or Vonage or any type of VoIP. These services cut off the low and high frequencies, which include the frequency we measure. Otherwise, any traditional phone line or cell phone with good connectivity will work.
