Nemesysco is an Israeli company that makes lie detectors and other products based on voice analysis. They have been used in airports in Israel and Russia, by insurance companies and social security helplines in the United Kingdom and sold to consumers. It has raised controversy about privacy and whether is it scientific or not. Users have claimed savings, mostly by subjects being more honest when told they are subjected to a lie detector. The CEO is Amir Liberman and the Executive Chairman is David Ofek. Their trademarked method is called Layered Voice Analysis (LVA), a kind of voice stress analysis.
Local authorities in the United Kingdom have used lie detectors from Nemesysco for social security helplines. This drew criticism for not publishing the results of tests and for flagging innocent but nervous callers. The latter criticism was, however, misplaced, since investigation of the workings of Nemesysco's products has shown them incapable of detecting vocal signals of nervousness. 
A 2006 study at the University of Florida for the Counterintelligence Field Activity concluded that LVA did not show any sensitivity to the presence of deception or stress. A 2008 study funded by the National Institute of Justice found that neither LVA nor the competing Computer Voice Stress Analyzer (CVSA) were able to detect lies better than random, but its use does deter people from lying, the bogus pipeline effect.
In 2007 two Swedish professors of linguistics, Francisco Lacerda of Stockholm University and Anders Eriksson of Gothenburg University, published an article called "Charlatanry in forensic speech science" in the International Journal of Speech Language and the Law. Here they examined the workings of a Nemesysco product, and showed that it behaved in pseudo-random fashion when purporting to identify spoken lies. Nemesysco demanded that the article should be withdrawn from the online version of the magazine, and the publisher Equinox did so. Nemesysco's lawyers then sent letters to the Swedish professors where they threatened to sue them for defamation if they published similar articles again. This resulted in criticism of Nemesysco for trying to silence academic research, and of the publisher for not understanding how to manage a scientific journal. The Royal Swedish Academy of Sciences branded the company's behavior a "serious assault on research freedom".

Layered Voice Analysis
Layered Voice Analysis (LVA) is claimed by Nemesysco to give an understanding of a subject's mental and emotional state by detecting the "emotional content" of his or her speech when answering questions. LVA is said to identify stress levels, cognitive processes, and emotional reactions. Nemesysco say that it is not a voice stress analysis technology, and instead uses their own unique patented technology to detect "brain activity traces" in a subject's voice via a wide spectrum analysis.
