COMMENTS FROM BAKER-DVSA USERS

•I have found the DVSA program a very useful investigative tool that is readily available for investigations on a daily basis if needed...I look forward to updates in the Certified Training Course and highly recommend the DVSA software.
Peter J. Breitnauer, Det. Lt. Kenmore Police Dept., Kenmore NY 14217

•I'm having difficulty describing the new DVSA system, but the best word that comes to mind is "Eureka!" It offers many advantages over what we've had in the past. Having been an examiner since 1974, I've used everything from a PSE-1 to the PSE-2000. The DVSA is portable, requires NO mechanical manipulation, NO adjustment of volume controls and all test recordings and charts are automatically saved to the computer hard drive until such time they are deleted. The DVSA is simplicity personified. Having been an examiner for many years, I initially felt that I only needed transitional training to DVSA. Instead, I took the 60 hour training course and readily discovered that it was exactly what I needed. The course was targeted toward the new DVSA program and covered all aspects and recent advancements in forensic voice stress analysis. The four examiners from our department, who took the course, are all well pleased with the results they are now getting.
Many thanks for your help.
Dale Smith, CID, Ouachita Parish Sheriff's Office, Monroe, Louisiana

•DVSA is great…don't get to use it as much as I like.”
Lt. Ken Simpson, Internal Affairs, Cleveland, TN Police Department

•…, since our recent class I have heard nothing but rave reviews
concerning the ease of use, portability, and results. I am currently to
begin approximately 50 new preemployment exams next week. I can't say
enough good about the software or the instruction you gave the class. DVSA is, in my opinion, the Only way to go!”
“I gave your (DVSA) program the highest remarks…and the results are great. (Fire) Chief Hill  and I love the program, we use it a lot.”
Kenneth Gibbs, Chief Arson Investigator, (retired) Monroe FD, Monroe, LA

•“I have been an active voice stress analyst since 1997, having been trained initially with the Diogenes Lantern system. I also conducted training on the Lantern for Diogenes in Colombia and Mexico. I have also used the Baker-DVSA in Ecuador, Guatemala and Colombia and have trained people in DVSA in each of those countries”.
“The major differences I see is the ability of the DVSA to allow more exact comparisons of the graphics. When I compare the accuracy in analyzing derived stress patterns, I am convinced that the ability of the analyst to compare voice patterns of the exact or nearly exact time lengths makes the DVSA more accurate than the Diogenes Lantern. The DVSA, which allows the analyst to highlight exact time lengths and reproduce patterns more closely, provides the analyst with a more accurate printed pattern to analyze” .
“I just ran 4 recordings using a 25 question screening format and 2 MZOC's. With the zoom function I was able to isolate the answers on the 25 question test , recording was about 3+minutes, got great graphics.”
Lt. Col. Mike Savage, US Army (Ret), Guatemala. (Former DIOGENES DIRECTOR OF OPERATIONS.)

•"The DVSA is working nicely. I am using it as the primary for waveform..."
Law Enforcement Analyst, U.S. Air Force Research Laboratory, Law Enforcement Analysis Facility, National Law Enforcement & Corrections Technology Center.

•“I have had the opportunity to use and study the Baker-DVSA on numerous testing situations. I have found the derived stress patterns of the same-recorded utterances from the Baker-DVSA, Lantern, and the PSE –101 are essentially the same from all three instruments… Based on this comparison in the use of these three instruments for charting purposes, as a Certified Stress Analyst, and President of the International Society of Stress Analysts, it would be (my) opinion that any previous validation study conducted with the PSE and Lantern would also be applicable to the Baker-DVSA, by ISSA.”
Marvin “Bud” McCorkle, President. International Society of Stress Analysts. Interim President, American Polygraph & Voice Stress Analysis Association.

•“[We] researched the opportunities worldwide of systems which use the science and selected DVSA as technically the most advanced, whilst adaptable (i.e. your willingness to develop the system to suit the UK requirements).”
Insurance Claims Investigators, United Kingdom.

•“We have decided to purchase the (BAKER) DVSA as we feel that it is more advanced and will be of greater assistance than the other systems (available ) … I have been working very hard to convince my friends in Mexico to use the system… I have convinced the Director of Internal Security for Chile to acquire the Baker DVSA. He was very impressed with the demonstration of the system… was able to work the program very good and did an analysis of several tapes that we had already completed investigations on and knew the answers to. Yesterday he (R. I.) presented the DVSA to the Argentine Security Forces Command Staff. They were impressed be cause we could show that the results of the case were the same as the analysis… I think that they were actually preparing to purchase the CV SA until my husband demonstrated the DVSA… Since we were able to show them that your system works and the cost is 1/2 of the CVSA” –

·        As far as I am aware of, I am the only person that has been trained by the three (3)         leading companies that manufacture and distribute Voice Stress equipment/programs.  Those companies are Humble's NITV, William Ames' Diogenes Group and Dr. E. Gary Baker's DVSA.

I can say unequivocally, Dr. Baker's program is one that surpasses all others.  Dr. Baker has been successful in developing a program that a trained examiner can employ with ease and also be accurate.  The training is so fluid and presented in a way that I have never witnessed in my 25+ years in law enforcement.

Dr. Baker has surely taken the world of Digital Voice Stress Analysis to another level by not only keeping up with today's needs, but providing tomorrow's' needs, today.

·        We have been using the DVSA and having good results.

Probably the best DVSA case we have had so far was this:

Citizen reports that several of his vehicles (work trucks) were burglarized and that a lot of tools and equipment were taken. Very little physical evidence was recovered and of course the victim had no serial numbers for any of the missing items. When asked about suspects, the victim named a former employee who had also been dating his daughter, and who had left on bad terms. The victim also seemed fairly certain that this person was the offender. The assigned detective followed up on that angle and interviewed the former employee. Unfortunately the former employee could not provide any alibi for himself and actually stated that he wished he had committed the thefts because the victim owed him money; thus he could not be excluded from suspicion. The suspect was adamant that the he did not commit the thefts and agreed to a DVSA examination. I gave the suspect three DVSA exams using the GQT format. All three tests clearly showed “no indication of deception”, and the suspect was eliminated. As it turned out, the real thieves were caught about six weeks later and confessed to the crime during their interviews-the original suspect had nothing to do with it.

All of my DVSA tests so far have been substantially similar in that we have been using it to eliminate possible suspects rather than using it to induce confessions from known offenders.

·        Guatemala’s SUPERINTENDENCIA ADMINISTRATIVA TRIBUTARIA (SAT), the equivalent of the U.S. Internal Revenue Service (IRS) now requires DVSA for employees.  They no longer use polygraph for screening and investigations.
