KishKish just came out with a VSA based Lie Detector version for Skype users.
They offer a free 10 days trail you can use.

You'll need to record a Skype conversation and then use the playback to see the VSA results.

Check it out at: http://www.kishkish.com/sam/vsa

Hello KishKish,

please let me know what is a relation between a Lie Detector machine and VSA application offered by you.
One can lie and your software shows no voice stress,
sometimes your software shows voice stress but there is no lie involved.
Could you kindly show some real life examples in support of your claims that your software can detect a lie.

The fatal flaw of VSA tests.  They're more voodoo; they take a partially or completely irrelevant physiological factor(s) and then claim that said factor(s) divine lie from truth.  Evidence for the assertions is lacking, incomplete, fudged, and/or not in keeping with the scientific method, but that doesn't stop any of the purveyors of these things.

Did you know a VSA box goes for thousands of dollars, as does an analog or computerized poly?  And the same people who sell these contraptions do the research or hire their buddies, often in the same business, to do the supporting research.

Conflicts of interest?  You be the judge...

You can try the LIAR LIAR software at http://liarliar.sf.net

As far as I know, this software utilizes various plugins for stress detection (microtremor, etc).

I haven't personally tried it yet, but I have read a review on it on some site (I forget where) and they gave it a high score.

I also use LiarLiar (http://liarliar.sf.net).  It seems to the best (most accurate) CVSA software I have tried.  Be aware that you need to have a high quality microphone w/o any type of noise-cancelling features.  Basically, you need to provide a signal as close to the original as possible.  In informal testing, I have anywhere between a 75-90% success rate with LiarLiar.  And the best thing is its free!

The Liar Liar software analyses aspects such as pitch and tone - both of which can be
controlled and / or manipulated by the examinee.

More BS for the gullible.

Try a coin flip. It has undeniable accuracy of 50%
