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.
