ABOUT AVSAPRO

Avsapro Global South Africa produces the worlds leading Voicestress Detection software systems since 1995. Designed and created in AI, utilising an AI neural network to score the Lippold microtremor in voice waves. Our proprietary scoring algorithm was developed using >250 known solution, recorded polygraph examinations. The voice tracks on hi fidelity VHS recorders were matched to the polygraph scores in instances where Examinees admitted guilt and made confessions. These were blind scored multiple times by three experts and verified by AI. Our neural network contains >6,000 pre-scored samples of “No”, to achieve reliability equal or greater than conventional polygraph systems that utilise pneumatic vacuum tubes and pressurised rubber bladders.

Avsapro Veritas is the only voicestress systems utilising Lippold microtremors and AI driven technology in combination. We have a thirty one year history of innovation in Voicestress Detection and Polygraph technologies.

Avsapro Millennium is the predecessor to Avsapro Veritas, but it remains in use in the field today due to its enduring popularity and proven reliability in real-world testing environments, where results matter more than marketing claims.

Avsapro Veritas is our newest Voicestress Detection technology. It has a fresh new look. It produces Client Ready reports. The face of Veritas is virtually identical to our EVC Polygraph system software. This enable users to seamlessly transition from Veritas to Polygraph by purchasing our EDA system, or BP sensor and TGAM brainwave sensor. The EVC polygraph system also provides a voicestress channel, making it a 4 channel system. (Refer www.evc-polygraph.com )

Both Voicestress systems incorporate popular and validated built-in Question Constructs such as Backster, IZCT, AFMGQT, Utah and POT. Users may create their own constructs.

It currently runs in MS Windows operating systems only, for the time being.

AVSAPRO is a South African company that conceives, designs and produces crime prevention technology. At the heart of Avsapro systems lies a powerful AI neural network (Voice Stress Detection Engine). Our programs are Avsapro Millenium and Avsapro PCAT

OUR FOUNDER

THE OG - CLIFTON COETZEE

Clifton Coetzee is one of SA’s leading authorities in the science of forensic psychophysiology having a career spanning over 30 years. Clifton is a manufacturer accredited polygraph Instructor and the developer of AVSAPRO, the only automated, digital voice polygraph system worldwide. Cliff has investigated fraud and deception in all it’s forms for over twenty five years practising and instructing polygraphy, voice-stress analysis, statement veracity analysis and forensic interviewing techniques.

Clifton’s first manual for forensic psychophysiologists and certified fraud examiners was catalogued by the FBI training academy in 2000.

His investigations included large scale bank and insurance fraud, usually committed by employees. Cliff received his training from former US and Israeli police and intelligence experts and has worked on behalf of listed IT logistics companies based in the UK, USA, Spain, Lebanon and Australia. He has also studied the work of many early experts in the field of statement analysis, the different techniques, applications, differing schools of thought; such as Statement Veracity Analysis, Credibility Based Content Analysis, Statement Content Analysis (SCAN) and Scientific Analysis as taught by Avi Sapir of the Laboratory for Scientific Interrogation Inc, Arizona, under the acronym ScAN.
