- Voice_risk_analysis abstract "The Voice Risk Analysis or VRA, also called Voice Stress Analysis (VSA), is marketed in the UK as a lie detection technology developed by Digilog. It is said to work by detecting the changes in the voice of the subject when he is lying. The developers maintain VRA technology works by measuring slight, inaudible fluctuations in the human voice that indicate when a speaker delivers words under stress and reportedly, when that stress is generated by an attempt to deceive. The caller's voice patterns are analysed by computer and thereafter assessed a high or low risk of deception. The fundamental assumption in voice risk analysis holds that individuals engaged in lying experience added stress. Increased risk of detection and a greater potential payoff serve only to add to the degree of stress experienced. Aside from other physiological responses, particular increases in voice pitch, frequency and intensity are said by the developers to be indicative of deception.Marketed to customer contact/call centres, the promise of a lie detection product has particular appeal to insurance claim handlers and government agencies involved in processing welfare benefit claims. As with the polygraph, academics argue that there is no scientific basis to support the manufacturer’s claims.".
