What Is The Need?
Ever since people acquired the capability of speech, lying and deception
have been inescapable facts of everyday life. Conventional lie detector
results are not admissible in court because people can physically
alter their behavior to appear to be telling the truth. The human
voice on the other hand, cannot be manipulated. It is a complex
instrument for expressing a full range of emotional and cognitive
states of mind, that even the best voice training in the world cannot
overcome. Better yet, vocal segments can be gathered and analyzed
over the phone, taken from TV or radio shows, or even in a face
to face conversation, without the subject being aware.
What Is It Based On?
Did you know that the human voice consists of six global levels?
1) The textual level - the words we speak.
2) The identifying level - unique elements in every individual's
voice.
3) The intonation level - the way we express ourselves.
4) The emotional level - an uncontrolled element of the voice that
indicates the level of excitement and the emotions they attach to
what they are saying.
5) The cognitive level - an uncontrolled element of the voice that
indicates the amount of conflict or agreement with the spoken sentence.
6) The physiological element - indicates the stress, physiological
alertness and general physiological condition. Truster technology
examines the emotional, cognitive and physiological patterns in
our voice to deliver accurate messages regarding vocal segments
of a conversation or broadcast.
How Does It Work?
Truster technology produces a computerized analysis of the speech
flow to distinguish between nonverbal emotional, cognitive and stressful
elements within the human voice. When all is said and done, a lie
is a deviation from how one would answer an obvious question such
as, What is your name? A subject may answer the exact same question
differently in different situations. For example, the reaction to
asking a subject how much money they made in a certain period will
vary depending on whether it is during a free conversation, job
interview, or legal proceeding. Lying or attempting to be faithful
to the truth requires much more exertion than answering an obvious
question, but it also depends on the circumstances.
The Truster technology's unique ability to mathematically calculate
emotion in the human voice makes it one of the most important breakthroughs
in the field of vocal lie and feeling detection. The operator's
level of expertise at testing subjects and interpreting the data,
combined with the awareness that different contexts can produce
different outcomes, is the key to achieving accurate results.
What Do The Results Mean?
The proper interpretation of the results is crucial to the process.
There are three main indications that a person is lying. When a
person is stressed, confused and excited all at the same time, chances
are that they are lying. However, very few people (1%) lie very
convincingly without any of the above symptoms because they do not
feel that there is anything wrong with lying, and/or they might
not feel a need to be faithful to the truth. The system will not
detect a lie if a dishonest person claims something happened and
genuinely believes it to be true. That is precisely why we recommend
using your common sense in analyzing the results Truster products
produce
Try to focus on finding deviations in the results. For example,
an honest person may get stressed, confused and excited while trying
to stick to facts exactly as they remembered them. An honest person
may feel that they are speaking the truth but actually be lying
to themselves. A person may state that they are going to overcome
certain obstacles, but may not truly believe in their capability
to do so. Truster technology will pick that up as a deviation, but
it certainly does not mean that the subject is dishonest. They may
merely be inaccurate, or unsure of their words, as the system will
display throughout the conversation.
Therefore, we recommend using your common sense to evaluate the
results, by considering the specific context of the conversation.
Truster technology is recognized as the most accurate tool for detecting
emotions in the human voice. The personal version, called Truster,
is best utilized as a decision support tool.
