Comments:
The CVSA was
developed based
on the
scientific research/studies
and work related
to the original
PSE. It has
evolved over the
years from an
analog to a
digital system
which is loaded
onto a
state-of-art
notebook
computer or the
military-version
notebook/hand-held
version. An
independent
survey
commissioned by
the U.S.
Military's
Special
Operation's
Command of law
enforcement
agencies
utilizing the
CVSA produced an
accuracy rate of
92%. Further
field studies in
2007 and 2008 by
the US Special
Forces in Iraq
produced
a confirmed
accuracy rate of
98%. This
finding was
mirrored by the
extensive
testing done in
2007 with a
number of major
metropolitan law
enforcement
agencies for the
CVSA II – all
found the
average accuracy
level of the
CVSA II with the
new FACT Scoring
Algorithm to be
96-98%. The
CVSA is the only
voice stress
analyzer whose
accuracy and
ease of use has
allowed it to be
widely accepted
and utilized in
both the law
enforcement and
the U.S.
military. |

Comments:
This is the name of
both the original
company and the
original voice
stress analyzer, but
that's where the
similarities end. In
its current
configuration, this
PSE is not
state-of-the-art.
The main drawback is
that it has no
automatic scoring
algorithm -
light years behind
today's technology.
Anyone considering
the PSE should
contact Chief Gary
York at the
Groveport P.D. (OH).
“After my
experience with the
PSE and its owner, I
feel confident the
CVSA will better
assist the Det.
Bureau in doing
their jobs.”
Following Detective
Dalton’s graduation
from NITV’s
Certified Examiners
Course, he wrote
“Having had an
experience going
through PSE training
with DEKTOR, NITV as
well as its
instructors are head
and shoulders above.
The CVSA technology
is up to date, with
1st class,
knowledgeable
instructors, and
ultimate
professionalism
company wide. A very
pleasing
experience... Thank
you!” A number
of agencies have
traded in their
PSE’s for the CVSA
II. The PSE is sold
mostly to P.I.'s.

Comments:
This system is remarkably similar to the Diogenes Lantern. Gary
Baker, a
P.I.
that
formerly
taught
for The
Diogenes
Group,
left the
company
in 2002
and
introduced
his own
system,
the
Baker
DVSA.
From
the
literature,
the
system
appeared
to be a
very
comprehensive
and
up-to-date
VSA.
However,
after a
careful
analysis
and
rigorous
testing
of the
Baker
DVSA, it
was
determined
that the
literature
was very
misleading
and the
system
appears
to be
simply a
copy of
the old
Diogenes
Lantern
(formerly
Verimetrics)
with a
few
cosmetic
changes.
This
system
also
requires
periodic
re-licensing
of the
software
which is
sold at
an
additional
cost. A
number
of law
enforcement
agencies
have
traded
in their
Baker
DVSA's
for the
CVSA.
Anyone
considering
this
system
should
read
this
article. According to the article, it appears that ‘Dr.’ Baker is not a
‘Dr.’ at
all, but
rather
purchased
his
Ph.D.
for
$249.00

Comments:
On
their
Web Site
under
‘Hot
Press
Release’
the
manufacturer
states
that the
Truster
was used
to
analyze
President
Clinton’s
statement
made on
January
26, 1988
in which
Mr.
Clinton
denied
having
sex with
Monica
Lewinsky.
The
Truster
found
that Mr.
Clinton
was
telling
the
truth.
In light
of his
later
admissions,
it
appears
that the
Truster
was
incorrect.
Other
reviews
of the
Truster
have
found
the same
results.
Recently
the
rights
to
market
the
Truster
in the
U.S.
have
been
purchased
by
several
different
companies
and it
is being
marketed
under
several
different
names as
“The
latest
in lie
detection/emotion
detection
technology”
and “The
DNA of
thought.”
Nemesysco
also
sells a
"Love
Detector".
