The SENSE technology is comprise of 4 sub-processes:

1. The vocal waveform is analyzed to measure the presence of local micro-high frequencies, low frequencies and changes in their presence within a single voice sample.

2. A precise frequency spectrum of the vocal input is sampled and analyzed.

3. The parameters gathered by the previous steps are used to create a baseline profile for the subject.

4. The new voice segments to be tested are compared with the subject's baseline profile, and the analysis is generated.

This whole set of input can be further processed by statistical learning algorithms to predict the probability of a deceptive or fraudulent sentence in the subject's speech. 

Another layer that is used in certain applications evaluates the conversation as a whole, and produces a final "Risk" or "QA" value.

SENSE Range of Emotions

The SENSE technology can detect the following emotional and cognitive states:

Excitement Level: Each of us becomes excited (or depressed) from time to time. SENSE compares the presence of the Micro-High-frequencies of each sample to the basic profile to measure the excitement level in each vocal segment.

Confusion Level: Is your subject sure about what he or she is saying? SENSE technology measures and compares the tiny delays in your subject's voice to assess how certain he or she is.

Stress Level: Stress is physiologically defined as the body's reaction to a threat, either by fighting the threat, or by fleeing. However, during a spoken conversation neither option may be available. The conflict caused by this dissonance affects the micro-low-frequencies in the voice during speech.

Thinking Level: How much is your subject trying to find answers? Might he or she be "inventing" stories? 

S.O.S: (Say Or Stop) - Is your subject hesitating to tell you something?

Concentration Level: Extreme concentration might indicate deception.

Anticipation Level: Is your subject anticipating your responses according to what he or she is telling you?

Embarrassment Level: Is your subject feeling comfortable, or does he feel some level of embarrassment regarding what he or she is saying?

Arousal Level: What triggers arousal in the subject? Is he or she interested in you? Aroused by certain visuals? This new detection can be used both for personal use for issues of romance, or professionally for therapy relating to sex-offenders.

Deep Emotions: What long-standing emotions does your subject experience? Is he or she "excited" or "uncertain" in general?

SENSE's "Deep" Technology: Is your subject thinking about a single topic when speaking, or are there several layers (i.e., background issues, something that may be bothering him or her, planning, etc.) SENSE technology can detect brain activity operating at a pre-conscious level.

Additional parameters currently under research:

Active Imagination: (Intensive cognitive processes) Measures whether your subject is engaging in thought requiring memory or imagination.

PAIN: Measures whether your subject is experiencing pain.

How Does It Work ?

The speaking mechanism is one of the most complicated procedures the human body is capable of. Just think for a moment how many muscles and body parts are being used in this process, and how well they should be synchronized...

First, the brain has to decide what should be said (a fairly complicated task for itself) then, air is pushed from the lungs upward to the vocal cords, that in time must vibrate to produce the main frequency. Now, the vibrated air arrives to the mouth. 

The tongue, the lips, the teeth and the nose space turns the vibrated air into sounds we recognize as phrases. The brain is closely monitoring all the events, and listens to what comes out- if we speak too softly, too loudly and is it understandable at all.

Due to this close attention the brain is using, every "event" passes through the brain will leave it's mark on the speech flow. SENSE Technology Ignores what your subject is saying, and focuses only on what the brain is broadcasting. 

The Lying Games...

Why do people lie? Humans, unlike other mammals, are capable of "predicting" or imagining the future. Most people can tell whether or not a certain response will cause them pleasure or pain. Lying is not a feeling, it is a tool. The feeling structure around it will be the one causing us to lie, and understanding the differences is crucial for making an analysis.

The SENSE technology differentiate between 5 types of lies:

1. Jokes - Jokes are not so much lies as they are untruths, used to entertain. No long gain profit or loss will be "earned" from it, and usually, little or no extra feelings will be involved.

2. "White Lies" - You know you don't want to say the truth, as it will heart someone else(!). White lies are lies, but the teller usually experience no stress or guilt.

3. "Embarrassment Lies" - Same as for white lies, but this time directed internally. You will loose nothing but the respect of the listener, most likely for the short term.

4. "Offensive Lies" - This is a unique lie, for it's intention is to GAIN SOMETHING EXTRA you couldn't gain else way.

5. "Defensive Lie" - The "regular" lie. You can't say the truth because it will heart you.

SENSE and Truster Technologies

The SENSE technology IS the old "Truster" technology, with several additions and improvements. The old Truster was all about emotions in the context of Truth / Lie, SENSE looks at emotions in general. (The "Lie" detection part still exists, but SENSE can for example detect "Love" or "Lust" or "Embarrassment" too.) The SENSE technology is protected by the same patent as Truster around the world, and an additional patent was filed in Israel at 1999 to protect some of the new additions. Although major parts of the technology are disclosed in the patents, Nemesysco reserved few crucial portions for specific detections unrevealed, as they are considered Nemesysco's most secret know-how.

SENSE and Sexual Arousal

When people get sexually aroused or feel in-love, strange things happens to them. The pupils get wider, the lips get reddish, the face skin gets red... all for the purpose of looking more beautiful. (not successfully all the time...)

We found out (by mistake, we must say) that the voice changes too. The increased excitement makes the whole voice higher and more concentrated. In many events, we play an act to the one we want, trying to make him/her think about us what we think he/she wants to think. Therefore we anticipate his reactions. 

The SENSE technology can detect the increased excitement (generally, not per segment as the ordinary excitement) and the heighten concentration and anticipation. 

This new feature of the SENSE technology can be used for entertainment and personal usage, as well as for much more serious uses such as sex-offenders and child abusers detection, and more.
