    The proven alternative to traditional polygraph testing

    The technology identifies various types of stress levels, cognitive processes, and emotional reactions that are reflected in different subtle properties of the voice.

    This information provides insights into the way your subject thinks, what troubles him, what excites him, what portions of his speech he is uncertain about, what questions require more of his attention, and what areas appear to be sensitive issues for the speaker.

    The technology is based on a proprietary set of vocal parameters found through research to correlate with key human emotions, and in various combinations to be able to identify deceptive intentions in “real life” scenarios.

    The technology was originally invented in 1997 by Amir Liberman, and has been progressed over time in consultation with experts from different relevant fields including psychology, criminology, phonetics, psychiatry and mathematics.

    When do people lie?

    from harm

    To gain

    a Joke


    Due to this variety in motivations and intentions, there is no fixed set of characteristics (physiological or psychological) that differentiates “lies” from “truth”.

    LVA detects a sharp change in the associated emotional reactions and assist you to expose risk and uncover the truth.

    Professionals in the field of lie detection know that there is no such thing as a “real” lie detector, since lying is not a unified reaction that is consistent at all times. Even the polygraph, the most known “Lie detector”, can only function properly in its pre-defined settings and in the relevant context. Simply connecting a polygraph to a person watching a video or performing any physical activity will render of course meaningless results.

    The polygraph – the most known lie detector BUT is it the most effective?

    Lying is a deliberate act by someone who has a definite plan to deceive or distort the truth.

    What is LVA used for?

    There are a wide variety of uses for this technology which we have utilized successfully for many happy clients. We utilize the LVA for:

    • Risk Segmentation for Insurance Companies – determining if a claim is a high risk for further investigation.
    • Pre-Employment Analysis – determining if a candidate does not have any hidden detail which can be costly and a possible concern for a business further down the line – questions are asked about issues you will not find in your standard employment checks.
    • Integrity Screening of current staff – in this day and age there is great concern over what the staff are actually doing, this can be related to giving out company information, making unauthorized payments or even committing fraudulent activities.
    • Incident Specific – this ranges from thefts of items to errors that have occurred. They are narrowed down in a pool of suspects for further investigation.

    There is no specific industry where this technology cannot be utilized. We have serviced clients from the majority of industries from:

    • Insurance
