Researchers found that frequencies in the human voice in (most are the 8 to 12 Hz range) are sensitive to honesty. When a person is being honest the average sound in that range is generally and almost below 10 Hz, and is usually above 10 Hz in dishonest situations.

All muscles in the body, including the vocal chords, vibrate in the 8 to 12 Hz range. This is considered a feedback loop, similar to a thermostat/heater that will maintain an average temperature by raising the temperature a little above the setting, switch off, and not come back on until the temp is a little below it.

Just as the temperature swings up and down over time, so too do the muscles tighten and loosen as they seek to maintain a constant tension. In moments of stress, like when you tell a lie that you dare not get caught at, the body prepares for fight or flight by increasing the readyness of its muscles to spring into action. Their vibration increases from the relaxed 8 to 9 Hz, to the stressful 11 to 12 Hz range. This is known to be caused by the production and release of a chemical, as explained in the Scientific American Article "Psychological Tremor" Vol. 224, No. 3.

Such of vibrations are a measure of stress levels of which change from moment to moment. Everybody knows that stress, also known as anxiety or being up-tight, can be brought on by a simple thought or memory; of a loved one's passing on, for example, or suddenly remembering some dangerous obsticle in the future. Some people have high average stress levels, and some have low, and averages changes from day to day along with mood. What all people have in common is that their stress levels are constantly changing within their current range, changes which indicate the "percieved jeopardy" or "danger" of statements being made. A lie is often dangerous, humiliating, or injurous to get caught at, so lies tend to stand out on stress measurments.

The X13-VSA is a revolutionary new software product that work with your PC or laptop computer for quick and reliable recorded truth verification. Anyone with a computer can use it.
