TRUSTER
FUNCTION DEMO
-
-
-
Sound
Wave-
Displays the subject's frequency as it is being inputted
in real-time. A red frame around
-
the
sound wave window indicates that the subject is under
general stress - that is,
-
nervousness,
expectancy or any similiar type of stress.
-
-
System Decision Window -
Displays the system's decision
on the screen: "Telling the Truth", "High
Level of
-
Excitement",
"Confused", "Subject is not sure",
"Exaggerating", "Inaccurate", or "False
-
Statement."
-
-
Truth Bulbs -
-
-
The
truth bulbs have several functions:
-
-
1.
When the system waits, all the bulbs flashing. If the
bulbs are not flashing that means
-
the
signature code you typed in the registration screen was
incorrect and you should
-
perform
the installation and registration again.
-
-
2.
During the calibaration, the bulbs are turned on gradually,
from both edges and
-
towards
the center, until the calibration is completed.
-
-
3.
During a test, the bulb's color is either green for truth
or red for inaccuracy. The level
-
of
inaccuracy is determined by the number of red bulbs, for
example, one red bulb - a
-
minor
inaccuracy, five red bulbs - probably a lie.
-
-
Truth
Stress Window -
-
-
Displays
the subject's truth stress.

SPJ & AVJ (Cognitive level indicator) -
-
-
SPJ
(Samples per Jump) - A pure value (unitless) expressing
the presence of the
-
relatively
low frequencies in the analyzed sample. (The existing
technology utilizes this
-
value
to characterize the cognitive level of the subject).
-
-
This
variable indicates two situations: In medium values (110%
- 170%) it indicates
-
doubts
in providing the answer, and in higher values (around
190%) it indicates that the
-
subject
is manipulating his or her voice, or that the subject
is being aware of his or her
-
voice.
In any case, this is a situation that does not exist when
the speaker tells the truth
-
and
is sure of what is said.
-
-
The
higher the SPJ values, the bigger the subjects emotional
conflict, up to values around 190%, where the conflict
turns into an attempt to manipulate the voice. It should
be noted that there is no way to know the exact individual
limit for each subject, and the value of 190% was determined
following a series of tests. On the other hand, a factor
such as hoarseness of the voice may have an unpredictable
influence on this variable. The values for this variable
are presented in a graph called SPJ.
-
-
AVJ
(Average Jump) - A mathematical value expressing the average
frequency in the
-
range
of flow frequencies (characterized by SPJ). The existing
technology utilizes this
-
value
to examine the degree of thought invested in the spoken
words.
-
-
This
variable measures the amount of thinking the speaker puts
into what is being said.
-
This
index is not presented in a graph, but it is used for
the process of characterizing the profile.
-
-
SPT
(Emotional Level indicator) -
-
-
SPT
(Samples per Thorn) - A pure (unitless) expressing the
presence of the relatively
-
high
frequencies in the analyzed sample. (The existing technology
utilizes this value to
-
characterize
the emotional level of the subject).
-
-
This
variable indicates mainly the level of excitement. Values
over 100% indicate a
-
growing
excitement level. SPT is the main raw index for calculating
the excitement level.
-
In
principle, a higher value for this variable indicates
a higher level of excitement. The
-
"Excitement"
graph displays the system's weighted decision concerning
the subject's
-
excitement.
-
-
Global Stress - (JQ)
-
-
Indicates
mainly the subjects global stress. A higher value indicates
a higher level of
-
stress
for the subject. The processed results for this variable
are presented in the "Global Stress" graph.
-
-
Excitement
Graph -
-
-
Displays
the level of the subject's excitement.
-
-
Calibration Button -
-
-
During
the calibration stage, the system will perform several
continuous examinations of different speech segments defined
as the truth. Values are collected into a table for concluding
the calibration stage and constructing a neutral speech
pattern.
-
-
While
taking into considering the basic assumption that each
and every test subject is
-
psychologically
unique and different, the system will set an average value
for each of the sound wave parameters upon the completion
of the calibration stage. An additional value expressing
the standard deviation from this average and an additional
value that - with the completion of the analysis proccess
- will ultimately be used to determine the degree of reliability
of such variables.

Show
Profile Button -
-
-
When
you are through testing the subject, this button is used
to review and save the
-
subject's
session in the form of a report. See "Reports"
below for more information.
-
Show Reports Button -
-
-
Activates
the reports display button. Where you can read over and
evaluate old
-
summaries.
