URL in The Economist, October 5, 1996, p. 46. http://www.cmiatl.com/ Crisis Management International, Inc. CMI provides crisis management services relating to "hot" threats of violence, workplace violence prevention, and post-incident crisis intervention. In addition, CMI provides threat of violence and crisis response training, psych-claims management assistance, and SCAN analysis, which is a deception detection technique.
This reminds me... Years ago, somebody developed a technique called "Voice Stress Analysis," which was supposed to detect small variations in a person's voice in response to stress. Not exactly a lie-detector, but it was supposed to do nearly the same thing. Does anybody plan to analyze the debates for stress? Is there software to do this?

Pardon me for butting in. Some remailer says I post too much, and I should cut out some. They didn't say which posts I should cut out, tho'. Anyway, as I understand it, the current technology in voice/stress analysis goes way beyond the polygraph at its best (current) level of technology. There was at least one agency that did voice analysis during the Simpson debacle, and the results were (as I recall) very promising. Apparently, a person who can beat a polygraph cannot beat a voice/stress analysis. BTW, the rule for these debates (as all presidential discourse) is: "He's lying." "How can you tell?" "His lips are moving."

The original device was the PSE, the psychological stress evaluator. It was, as still is, sold by a company called Dektor. It is located in the DC area (Maryland?) and is run by a group of ex-spooks. It's been around for 25 years or so. S a n d y ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PSE/VSE etc relys on a random 8-14 hz fm modulation appearing in the the 3rd formant band of the voice... the Dektor PSE retailed for approximately 5k in the early 1970's the hagoth hs-2 was the early 80;s for 2k .. I bought 2 VSE units based on a new chip for 89.95 apiece recently... this was on an article appearing in popular electronics in 1995 no software as of yet and it would be probably a FFT or DFT based algorithm running on a sound blaster DSP(hardware DSP only) or as software on a fast 150 Mhz + pentium I can give the basic facts known... it is a truth detector only(not a lie detector), background music shows up a stress... and scrubbing the modulation shows up as constant stress or "possible decption" truth is indicated by the modualtion showing up randomly over small increments of time... the effect is caused by microscopic tremors of the larynx when the speaker is relaxed and truthful the larnyx is relaxed and the random modulations show up,(or the speaker believes what he is saying to be the truth, when lying or under stress the larybx tightens and the random modulations disappear indicating stress... it would be nice to have it in software... to run on a laptop soundboard and spread to the net as widely as pgp... cheers a cypherpunk
