Computer Voice Stress Analysis

What is Computer Voice Stress Analysis?

Voice Stress Analysis measures subtle changes in vocal quality due to the increased tension that ineluctably accompanies deceptive utterances. The tension is a function of the autonomic nervous system and can not be controlled or hidden by the subject being tested. In fact, by the Law of Inverse Effect, the harder they try to control it, the more tension will register.

Who uses it?

Different versions of Voice Stress Analysis are now used routinely by government intelligence agencies, probation services, and law enforcement departments throughout the country. The Berkeley Police Department, which was the home of the original polygraph, now utilizes Voice Stress Analysis as a key investigative tool in major crime cases and uses it exclusively in their background screenings for new officers.

What is unique about our technique?

Our approach differs from other agencies in several significant aspects:

  1. We are the only ones to combine Computer Voice Stress with two channels of Galvanic Skin Response, which is the most accurate physiological measure of the traditional polygraph. By triangulating modalities, we are able to replicate findings and give more accurate final judgments.
  2. Unlike other Voice Stress Protocols, we are able to score not only the answers to "YES/NO" questions, but also longer narratives. This permits a more comprehensive judgment of the critical issues.
  3. Our approach uses our proprietary Statement Analysis Lexicon in an algorithm that selects out critical diction and coherence structures for special coding and differential scoring. This additional analysis ensures the highest degree of accuracy.

Because our staff has strong clinical psychotherapy training, we are able to communicate results in a far more empathic and intelligible manner than other testing services. We are also able to offer very specific follow up suggestions for further investigation or treatment. This is most helpful when dealing with sensitive family and personal issues.

Forensic Hypnosis

What is Forensic Hypnosis?

Forensic Hypnosis is a specialized application of traditional clinical technique. It is used by investigators to enhance the memories of victims and witnesses of criminal activity. It can be used to recover the missing digits from a getaway car license plate, the composite facial features of an assailant, or the exact sequence of events in a complicated fast moving crime scenario.

What is unique about our approach?

  1. Because of our strong clinical background we are able to sort out real memories from fantasies and confabulations.
  2. We are acutely sensitive to the unconscious meanings of words, images, body language, and subliminal tonal emphasis. This is very important for being able to recognize and eliminate indirect suggestion, which might contaminate the accuracy of recovered memories.
  3. By using our proprietary Statement Analysis Lexicon we can evaluate the substance of recovered memories based on the form and structure of the utterance. This technique permits a specific Credibility Quotient to be assigned to each key fact segment.

By running Computer Voice Analysis during the actual hypnosis sessions we are able to locate in real time areas of heightened stress. Pinpoint follow up questions can then help distinguish the anxiety of real trauma from the stress associated with intentional deception.

How do we differ from other statement analysis services?

 

   

  1. Because of our strong clinical psychology background and experience, we are able to interpret not only the form and structure of communications, but also the deeper motivations and unconscious messages. Years of working with Thematic Apperception Test stories allow us to identify recurrent themes in a longitudinal series of messages and documents.
  2. We are able to devise the most psychologically effective interview and interrogation questions that utilize the subject's own defensive structure to get truthful answers and confessions.
  3. We are able to offer specific strategies for diffusing difficult situations before they actually become dangerous and violent.
  4. Using our proprietary statement analysis software (F.A.S.T.) we are able to batch analyze even very long documents in a timely manner, and locate those critical segments that require expert scrutiny and immediate operational attention.
  5. By integrating Computer Voice Stress and Forensic Statement Analysis we are able to evaluate not only the Credibility Quotient of taped material, but also the stress levels of individual segments. In threat assessment cases this dual approach has proved invaluable in demarcating levels of danger.

In handwritten communications we are able to able to analyze the form structure of the writing, the spacing between phrases, the pressure variance in words, and retracing in key segments in order to help confirm the presence of thought disorder, anxiety, depression, rage, ambivalence, impulsivity, and hesitation.

Trust and Fidelity Assessment Instrument

This most effective questionnaire is designed to pinpoint truthful answers regarding sensitive issues of trust and fidelity. Using the methodology of Statement Analysis , the experienced practitioner can administer and interpret this tool effectively with 16 questions that can be applied to a variety of situations.

You will find this especially valuable in sorting out personal relationship issues. We provide private consultations for individuals who have intimacy and trust concerns.

This can be done by having the partner under suspicion fill out our concise 16 point questionnaire and sending it back to us for expert interpretation. The report will not only give you an objective answer to your trust and fidelity questions, but also address what might be motivating the behavior, and suggest specific problem remedies.

A typical consultation is usually under $200 and includes the opportunity to consult by phone or email with your Statement Analysis Professional.

We also offer a combined Statement Analysis and Computer Voice Stress Trust and Fidelity examination which can be conducted entirely over the telephone.

The cost for this service is determined by the complexity of the issues and the amount of consultation time.
