Voice Stress Analysis Software to be Awarded to State and Local Law Enforcement Agencies
Drugs, health status, age and alcohol do not affect the results.
The developer of software that analyzes a subject's voice for signs of stress is offering law enforcement agencies 100 grants for the software to aid them in determining if an individual is telling the truth or not.
"[Digital Voice Stress Analysis (DVSA)] is the most significant technological advancement in credibility assessment since the invention of the old polygraph," E. Gary Baker, Ph.D., the developer of the BAKER-DVSA software, stated in a news release. "We utilized Air Force Research Laboratory (AFRL) validated science along with my 35 years of conducting truth verification examinations and training examiners worldwide in developing the algorithms."
Dr. Baker touted several advantages of the BAKER-DVSA over a polygraph.
Assessments may be conducted with suspects, victims, witnesses, over the telephone, cold-case recorded interviews, public speech, intelligence technical intercepts, counter-intelligence, vetting of informants or during interrogations. Drugs, health status, age and alcohol do not affect the results. There are no known countermeasures. There are no "inconclusive" results, according to the Baker Group. However, polygraph examinations have 30% to 60% inconclusive opinions, the company said.
Over 2,500 U.S. law enforcement agencies use voice stress analysis including those in California, Florida, Tennessee, Illinois, Rhode Island, North Carolina and Georgia.
To aid agency personnel in the use of the software, the Baker Group Certified Examiner Course includes behavioral analysis, para-linguistics, neuro-linguistics, kinesics, removal of defensive barriers, question preparation and interrogation strategies to obtain confessions. Tuition is $1,500 per student. Classes sponsored by law enforcement agencies are held monthly throughout the U.S.
Grant applications for the system that normally sells for $9950 are available here.
