AVSA PRO - The VSA Evolution

The VSA Industry has been somewhat stagnant for the past decade. When Jean-Louis Gouin (Alpes-Software) developed Diogenes Lantern for Bill Ames, a new era began.

Sadly, Bill Ames passed away several years ago. Two of his erstwhile employees assumed the rights to continue distributing Diogenes and they employed Alpes-Software to re-label Diogenes as TDT. Alpes retained copyright ownership of the Diogenes program.

TDT (Truth Detection Technologies)- the name is somewhat of a misnomer as they have not produced any technology, despite their bold claims on their website.

In late 2009 I (Clifton Coetzee) made contact with Jean-Louis Gouin and we began a collaboration that has revolutionised the VSA industry.

Before I continue, it is important that one never confuses LVA with traditional VSA.
In my years of patient review of DOD technologies, I have found that LVA has reliability less than chance. Therefore I dismissed it totally in 1998, 200, 2002 and again in 2004. Since 1998 many LVA renditions have come to the marketplace:
Truster; Truster Pro; Tipi; Vipre/Vypre; SVX13; SVX13A; TVSA13;

The only true VSA applications as at current time ( May 2011) are AVSA Pro; CVSA; PSE5128 and TDT (Diogenes)

Interestingly, Diogenes Lantern was the only vsa program to have received a modicum of validity in scientific validation reviews, almost a decade ago.

The good news is, that Jean-Louis Gouin wrote Diogenes and it is the grounding for AVSAPRO. The spectrograph capture window in Diogenes and the general layout will be recognised in AVSAPRO, but that is where all similarity ends.

Where Diogenes (now TDT ) was a manual vsa program, AVSAPRO is fully automated with evolutionary features.

No longer does an examiner have to cut and highlight or tab the required CQ / RQ responses. AVSAPRO is equipped with validated question protocols and auto captures the responses required. Each question in a protocol is rolled onto the screen only when the preceding question has been asked, answered and captured. Questions can be re-asked without affecting the numerical allocation.

AVSAPRO automatically rotates the RQ's in subsequent charts (exams)

AVSAPRO maintains consistent cadence control, which in turn produces consistently reliable results. At the end of every question, the examiner habitually presses the response key, which emits an audible answer cue for the examinee 1,5 seconds later.

As the examinee has already recognised the question approximately 1-1,5 seconds before quesion terminates, the required Onset Delay phase of 2-2,5 seconds has been satisfied.

AVSAPRO is equippped with extremely versatile and unique filing alternatives. Tests can be recorded into any directory on the pc or direct to removable media.

Full recall is available via either of two independent methods.

Tests can be run in auto mode or manual mode. Scoring may be effected manually (examiner) or by the neural network processor.

AVSAPRO auto scoring does not involve random application of unproven theories or electronic recognition of tone or pitch. AVSAPRO has been trained by the neural network according to Expert Human scoring of 000's of voice wavs, blind scored and rescored several times. Many known outcome solutions have been utilised to train the neural network.

It can be said that AVSAPRO is the first DOD technology ever to utilise Artificial Intelligence (AI).

Futue versions of AVSAPRO will make provision for scoring of multiple word utterance to a Dichotomous question. GSR and Cardio functions are to be added.
The future of DOD is AVSAPRO.

Continuing the AVSAPRO evolution. In late 2014, Clifton and Jean-Louis began to develop a ne web based application, AvsaPro Global.
AVSAPRO Global is the Gold Standard for a world standardisation of Voice Screening and Testing.
Global version will be freely downloadable from the internet. Users can choose the type of question template required; either for Pre-Employment Screening; Periodic Honesty Screening, or Felony Issues such as theft or fraud.

Globa; version has a question library to assist users in question selection to match the Issues or Screenings. The questions are colour coded and can only be selected for a matching colour field.

APA validated question constructs are utilised to maintain accuracy.
Cadence(timing) is controlled and the tests are easily run, by following simple instructions in the Facilitators Manual.

Ultimately a simplified report is produced. The tests and screenings are scored by a neural network processor, to deliver a high degree of consistency and reliability.

The human involvement has been further removed in order to demistify and decontaminate tests and results.

While the App is free to download, users must register online and pay a nominal fee to purchase tests (licences) in batches of 1, or 5, or 10, or 50, or 100.

Global version will cater mainly for high volume users who require accuracy and consistency.

However, Accredited Professional Examiners will have access to the Professional section where there is freedom question construction, but template structure is maintained to produce simplified easy to understand reports.

No longer will anyone have to employ expensive specialists and no longer will anyone have to pay exorbitant fees for specialist training.


Reliable Screening and Testing of personnel is about to become very affordable.
