X13-VSA “Dedicated to Truth”
"With only one click" - Your Personal Truth Verifier.
X13-VSA is an innovative, advanced and sophisticated
software system and a fully computerized voice stress analyzer that
allows you to detect the truth instantly. X13-VSA is based on an
ingenious new and old algorithm to detect vocal stress.
The X13-VSA technology was originally developed in
1980 for military use, and now you can use the same technology as they
use to detect lying and deception.
The software is clear, elegant, and so easy to use
that you can have it up and running within seconds.
Voice Stress Analysis is a type of lie detector which
measures stress in a person's voice. That makes it recordable, and means
it can be used on tape recordings older than VSA technology itself is.
The use of Voice Stress Analysis (VSA) as a lie detector became popular
in the late 1970s and 80s. Today is Voice-stress analysis, an
alternative to the polygraph as a method for lie detection, is already
widely used in police and insurance fraud investigations and by other
organizations.
In both principle and execution VSA is a simple technology.
Researchers found that frequencies in the human voice in the 8 to 12 Hz
range are sensitive to honesty. When a person is being honest the
average sound in that range is generally below 10 Hz, but is usually
above 10 Hz in dishonest situations.
All muscles in the body, including the vocal chords, vibrate in the 8
to 12 Hz range. This is considered a feedback loop, similar to a
thermostat/heater that will maintain an average temperature by raising
the temperature a little above the setting, switch off, and not come
back on until the temp is a little below it. Just as the temperature
swings up and down over time, so too do the muscles tighten and loosen
as they seek to maintain a constant tension. This is known to be caused
by the production and release of a chemical, as explained in the
Scientific American Article "Psychological Tremor" Vol. 224, No. 3,
1971. In moments of stress, like when you tell a lie that you dare not
get caught at, the body prepares for fight or flight by increasing the
readyness of its muscles to spring into action. Their vibration
increases from the relaxed 8 to 9 Hz, to the stressful 11 to 12 Hz
range.
Such vibrations are a measure of stress, levels of which change from
moment to moment. Everybody knows that stress, also known as anxiety or
being up-tight, can be brought on by a simple thought or memory; of a
loved one's passing on, for example, or suddenly remembering some
dangerous obsticle in the future. Some people have high average stress
levels, and some have low, and averages changes from day to day along
with mood. What all people have in common is that their stress levels
are constantly changing within their current range, changes which
indicate the "percieved jeopardy" or "danger" of statements being made.
A lie is often dangerous, humiliating, or injurous to get caught at, so
lies tend to stand out on stress measurments.
The X13-VSA is a revolutionary new software product that
work with your PC or laptop computer for quick and reliable recorded
truth verification. Anyone with a computer can use it.You will be in a
position to detect deception and verify the truth and you can record
conversations for later analysis. You may analyzed from TV or radio, or
even in a face-to-face conversation, without the subject being aware.
You can take any recorded conversation, record
yourself, spouse, friend, lover etc., (Audio Recording Software is
including in the package), save it as a normal Windows wav file and then
let X13-VSA analyze it. Of course when you do this make sure you obtain
consent from the person whose voice you are analyzing!
Once you have the file, you can run an analysis and X13-VSA will save
the results. After the analysis you can play these results. X13-VSA
singles the presence of a lie by special beeping and via the Frequency
Analyzer.
X13-VSA is effective in ANY SITUATION and is
applicable to ANYONE, including but not limited to: Criminal
investigations, violent crimes, robbery, internal affairs
investigations, or pre-employment examinations, insurance fraud
investigations, screening (eg: Airports) Check of visa/passports,
Witness Statements and much more. The use of X13-VSA is limited to your
imagination. X13-VSA is a fullcomputerized voice stress
analysis software.
X13-VSA is one of the most advanced Voice
Analysis systems ever and the easiest to use. It is powerful and it
go deeper and faster than any other voice analysis technology.
X13-VSA is a professional tool for the
Businessman or for Personal use, Governments and Security Organizations,
Law Enforcement agencies, Police, Military or Private Investigators.
X13-VSA is a decision support tool, and in
combination with your own judgment and common sense will be a great
assistance.
X13-VSA is
also a tool to detect lies you hear on your Skype phone. Just record all
your phone calls with an application like HotRecorder
(www.hotrecorder.com) and monitor them with X13-VSA voice-analysis
technology for lies and high stress levels.
X13-VSA has been sold to nearly 2,000 professional
investigators, law enforcement agencies, law firms,
journalists, businessman's and private persons from around the world.
The X13-VSA technology is the most advanced Voice
Stress Analysis system that has yet been produced to detect changes
in human speech and the cheapest system in the world.
The X13-VSA
technology is far superior to outdated systems such as TRUSTER, CVSA,
LANTERN and "Pocket Lie Detectors". X13-VSA IS THE TRUE SOLE SOURCE FOR VOICE
STRESS ANALYSIS SOFTWARE.
No one can lie to
you any more because with X13-VSA you know what your friends and clients
think about you...
What's the difference between X13-VSA and a polygraph? A
polygraph measures for physical stress, just like X13-VSA, but a polygraph
requires you to be attached. X13-VSA doesn't. You can also use it on
pre-recorded voices.
Enjoy the newest technology and our support.

instructions and easy to use installer/uninstaller, built-in Self-Test
diagnostic program that lets you know if the system is operating
correctly, Frequency Analyzer and Audio Recording Software.
