Several years ago the Pakistan government requested to purchase VSA technology. We were advised that Pakistan Intelligence Services and thus the government was supporting the anti US Taliban terrorist in Afghanistan. We chose not to deal with Pakistan.

Comments from our Law Enforcement Clients
Louisiana Department of Justice, Special Agent Jennifer Smith
I love the program!
Walter J. Daigre, Forestry Enforcement Program Manager
LA. Department of Agriculture & Forestry
This is a wonderful tool. It has helped me eliminate suspects and get to the right suspect in a speedier manner so I could focus on more. This is the ultimate equalizer. The bad guy now no matter how well his lie is rehearsed this program shows you what only he knows at the time. Great program!
Capt. Bobby Irvin, Chatham County Sheriff’s Office, Savannah, GA
I have been using DVSA for about 5 years. This has been incredibly useful for both criminal and administrative cases. I have had positive outcomes for which every case for I have used DVSA. All investigators need DVSA as an investigative tool.
Detective Travis Savoy, Jefferson Davis Parish Sheriff’s Office
(Sergeant, Louisiana State Police, (Ret)
At least one of the top 5 courses I have ever attended in my law enforcement career. Dr. Baker brings to the table over 45 years of expertise in voice stress analysis. An instructor who is knowledgeable in the field of interviews and interrogation, and determining deception. A must have course to add to any “toolbox”.
Detective Peter Normandin & Detective John Lee, Niceville Police Department, Niceville, FL
” Dr. Baker is very knowledgeable on this course. Easy to talk to and get answers. Quite enjoyable, Thanks. ” ” Good class and great tool.”
Detective Christopher Covelli, Lake County Sheriff’s Office, Waukegan IL 60085
Dr. Baker was an awesome instructor. It is clear he is extremely experienced in this field. Dr. Baker took time to answer all of our questions and ensured we all have a clear understanding of all topics associated with VSA. Dr. Baker goes above and beyond and even makes himself available by email / cellular for any questions we may have after the class. I learned so much in this class and I owe it all to Dr. Baker — a huge thank you to him for all of his teaching.
Chief Thomas Scully, Orland Hills Police Department, Orland Hills, IL
“As a police chief with more than 20 plus years of service, I have attended countless training classes. By far, this class was the most valuable. The material presented along with the instructor’s subject knowledge and experience make this a “must take” course for anyone charged with investigating crimes. The time and money spent were well worth it. The most informative and interesting class I have attended.”
Detective Sgt. Dan Kuttner, St. Charles Police Department, St. Charles, IL
I attended Dr. Baker’s Digital Voice Stress Analysis certification class. During the same week of the class, St Charles Police was actively investigating an Aggravated Domestic Battery to a Child incident in which a toddler was severely beaten. The suspect was taken into custody and agreed to take a DVSA test, in which he indicated deception. Through further interviews wherein the suspect was confronted with the test results, the suspect provided incriminating statements, which ultimately resulted in a significant prison sentence. The DVSA test proved to be a valuable tool the first time our agency employed it, and on a very serious offense. We have used the DVSA with similar positive results in many subsequent cases as well. It continues to be a positive asset in our investigations.
Editor’s note: This was Detective Kuttner’s very first DVSA examination after graduating from the Digital Voice Stress Analysis Law Enforcement Examiner Course.
Jared S. McKee, Chief of Police, Plainfield Police Department, IN
Security Director , FireWatch Security Consultants, Inc., Plainfield, IN
Dr. Baker and the DVSA system is a real asset to the law enforcement/security community. Words alone cannot describe what a great tool Dr. Baker’s DVSA system is. I have been in the law enforcement field for many years and have had the opportunity to utilize several different truth verification instruments. My prior experiences left me with an overwhelming sense that most of these instruments were unreliable in the detection of deceit and in many cases taught poor user practices.
I absolutely encourage anyone who is currently utilizing other Voice Stress Analyzers to take a serious look at Dr. Baker and his DVSA system. Your only regret will be that you did not choose Dr. Baker’s DVSA system first.

DVSA has been an awesome tool for us!
- We utilize DVSA examinations when conducting Internal Investigations.
- In June of 2016, DCS began utilizing DVSA exams as a pre-hire tool in the hiring process for officer applicants.
Certified Examiners: 5
FY2017 (July 2016-June 2017):
Certified Examiners: 8
DVSA is the final step in the hiring process for us. We have a lot of steps – interview, criminal background, driver’s history, medical exam, drug test, psychological, DVSA. For the applicants that make it all the way to DVSA, the examiners conduct a “courtesy” test, even if the applicant DQs himself during the pre-interview review of the DVSA booklet. The applicants who aren’t offered employment after the DVSA either DQed or hiring managers opted to not offer employment due to something the applicant disclosed in the booklet/pre-interview. We consider DVSA a very useful tool!
Editor note: GADCS also uses DVSA for OPS / IA investigations.

ILLINOIS STYLE: Some buy an alternative tool for lie detection that they say seems to be reliable.
“I’m not saying it’s infallible,” Algonquin police Detective Sgt. Doug Lamz said. “But anecdotally, I haven’t seen it be wrong yet.”
Proponents say that voice-stress analysis is simpler, more portable, and less expensive than a polygraph machine. It uses a laptop computer and a microphone to monitor voice “micro-tremors” during suspect interviews, taking into account nervousness, stimulants and other factors.
In January, Lake in the Hills police became the first department in Illinois to use the voice-stress analysis software and testing method from The Baker Group. Lake in the Hills police Sgt. David Brey said that although the tool was valuable, especially in helping rule out suspects, test results were never the sole factor in any investigation. “It aids in the direction of an investigation,” he said. “It’s just another tool to help gauge whether someone is being honest with us. But it does not figure into pressing charges.”
The technology can be used quickly and doesn’t require a department to retain a polygrapher. “It could take a month to get a polygrapher,” he said. “But with VSA, I can do it right here, right now.”
Voice stress analysis technology still is in the proving stage for Illinois police officers and sheriff’s deputies. The state General Assembly approved it for use about a year ago, making Illinois one of the last states to adopt the 30-year-old technology.
Lamz said that just because the voice-stress analyzers are relatively inexpensive and easy to operate does not mean they are inferior to the polygraph. “I don’t think one piece of equipment is better than the other,” he said. “It comes down to the operator. You can’t beat the machine. You can beat the operator. It boils down to training and experience.”
Our mission is to develop and offer the very best tools and solutions to provide law enforcement, military and intelligence units with accurate testing for Truth Verification and Credibility Assessment.
“Truth is absolute!”
