By measuring and clustering the unique appearances in the voice we can tell many things, such as the level of "Adrenaline" in the blood (or other natural drugs), how well both parts of the brain "agree" between themselves, is there an internal conflict in the brain, does the brain go into Fight-Or-Flight (Stress) mode, did the subject want to tell us what he just did, how concentrated he is and many more.

True. And indeed, so what? Our unique technology doesn't measure only stress (the result of the Fight-Or-Flight syndrome), but tries to understand the complete emotional structure (excitement, pain, fear, cognitive activity and more) in each sentence your subject says. Then, the overall analysis algorithm evaluates the minor differences in each vocal segment from the others to reach a decision (both textual and graphical).

"Sense" technology is used mostly in our semi-professional and low-end products, designed for various commercial and personal uses, and is intended for free-conversation that is not intimidating in any way. The "L.V.A" technology must go beyond the free conversation pattern. In any investigation, may it be a polygraph examination or an ordinary questioning session, the subject knows beforehand if and where he plans to lie. Professionals will also attempt to use Counter-Measures to avoid being detected if they plan to lie. The "L.V.A" technology takes all these parameters into account, including the natural stress real subjects feel in any investigation.

Various governments, security forces and Universities tested the different version of "L.V.A" (the "TrusterPro" Technology and product) around the world. The researches so far tried to measure the technology's ability to detect lies and to reach an automated decision for the tested subjects. Those tests indicate that the technology can reach a very high accuracy level (some tests indicated it is even more reliable than the traditional Polygraph) and assist the investigator to reach his final analysis, but in no way can be properly used by untrained operators. Unfortunately, non of these governments work for us, and most of their research results as well as their identity are usually confidential. We respect their privacy, and we will do the same with your privacy requests as a client. Even though, one report made by the US Air-Force Rome Laboratories can be found in our researches page. These researches also showed a remarkable difference between laboratory cases (about 70% accuracy rate) and "real subject" criminal tests (over 90%). Nemesysco welcomes any type of research on its technologies and will assist the researchers with whatever needed.

Many times in life, the picture is not black and white. Not long ago, a president was recorded denying "sexual relations" with a certain lady. Today, when every thing is known - was he lying? By analyzing his speech and monitoring his emotions, we noticed a "Low Lie Stress" together with high embarrassment - indicating "guilt knowledge". (Meaning: he knew he did something wrong, but found the way to put it in words that will not make him lie). Many of us do that every day, and so does your subject. By monitoring the way your subjects feel, you will reach more leads, fine-tune your questions and get to the truth faster. Knowing, for example, that your subject invents his stories as he goes makes your job to get his confession much easier.

Although one of LVA's mode of operation is used as a voice "lie detector", we prefer to think about our technology as an investigation focus tool. Polygraphs have a long history, and their reliability in the hands of professionals is proven. We suggest to use our technology for what it was designed to do, i.e. monitor and analyze emotions - and provide new leads in the beginning of the investigation, making your work more efficient.

No. Lies have a "tricky" nature, and the truth is always in the eyes of the speaker. We had a case in South-Africa where a man accused of man-slaughter was almost found innocent simply because he still didn't think that the guy he killed was human… once he showed extreme emotional reaction to the charges and further investigated he was recorded saying "This is not a man! It is a dog!"... The leads for your case are hidden in your subject's emotions. God - is always in the small details.

When the L.V.A technology is used to analyze one conversation, an emotional baseline profile of the subject is built based on his recorded emotional parameters, and the rest of the vocal segments are then compared to it to produce the analysis. The emotional profile is typically changing due to the circumstances and the subject's general emotion structure for that day. When we compare different complete conversations one to another, we try to compare their extended "emotion free" profile to learn HOW was the subject feeling in general, and to look for anomalistic behavior.
