Nemesysco

Nemesysco is an Israeli company that markets discredited voice analysis programs for fraud prevention, the detection of emotion, stress management, and other purposes. The use of the company's products by insurance companies, call centers, banks and airports has raised questions about whether the underlying technology has any validity.
History
The company was founded in 2000 by Amir Liberman, an Israeli businessman with no college education or formal training in mathematics, computer science or speech science. Despite the founder's lack of experience in the field and what one journal described as the program's "amateurish" programming, and by the Waupun, Wisconsin police department.
The company describes its software as "honesty maintenance" software, with applications including its use in human resourcing during interviews to determine the honesty of the applicant.
But after spending 2.4 million pounds on tests over three years, the Department for Work and Pensions revoked its funding for the program, saying that it "couldn't confirm that it represented any good value for money."
The program was also used for a study looking for links between the vocal performance of company executives and their firms' future financial performance.
Assessments
Government, academic and peer-reviewed studies have found major flaws in "layered voice analysis," the technique used by Nemesysco's products. A report for the U.S. Department of Justice assessing the program's ability to detect deception found that it "failed consistently," with high rates of both false positives and false negatives. A University of Florida study conducted a year earlier had found that LVA "misclassified the low-stress and truthful samples with great frequency."
A third paper, published in the International Journal of Speech, Language and the Law, classified Nemesysco's programs as "charlatanry" and said that independent analyses had authoritatively debunked the company's claims because "the evidence against them is just too overwhelming to motivate any more reliability tests."
That paper's findings were defended by David Beaver, a professor of linguistics at the University of Texas at Austin, who called Nemesysco a "bullshit lie detector company run by a charlatan."
A subsequent review, published in Homeland Security Affairs, found results similar to those of the three previous studies, showing that Nemesysco's LVA software was "unable to detect deception above chance levels."
