ITV is the only authorized distributor of CVSA instruments in Canada. The Computer Voice Stress Analyzer technology was introduced in 1988 and has since seen ever-increasing use in the law-enforcement community. The CVSA product has proven most effectively employed as a partnership between the cutting-edge computer software used to analyze specific voice patterns and the expert interrogation techniques used and taught by ITV. Used in this manner, clinical studies show the accuracy score of our product to be 98% with zero inconclusives.
  It does not require the subject to be attached to any wires, which makes CVSA ideal for pre-employment screening. CVSA is not affected by drug use, is not restricted to "yes" or "no" answers and can be applied effectively to pre-recorded interview tapes. It has proven its worth again and again in law-enforcement, corporate screening and background investigations.

The Software
Over the past twenty years, CVSA has evolved from the original analog instrument to an enhanced, digitized version with several technical improvements. A microphone is attached to the subject and during the interview process, the computer measures small frequency modulations in the voice. These inaudible variations, when detected, measured, quantified and displayed, can accurately determine the truthfulness of each statement elicited from a test subject.
As the subject speaks, each voice pattern is displayed on the computer screen, numbered and valued according to a patented scoring algorithm. The finished session is evaluated by the computer, rendering its findings of

  • 98% accuracy rate
  • Speed
  • Portability
  • Ease of operation
  • No inconclusives
  • Cost-effective
    (1/3 cost of polygraph)
