SFI RISK uses cutting-edge DVSA technology (Digital Voice Stress Analyzer). This allows us to directly test an individual’s answers in order to detect deception. DVSA records the human voice using a microphone, and the technology is based on the tenet that the non-verbal, low-frequency content of the voice conveys information about the physiological and psychological state of the speaker. Typically utilized in investigative settings, the technology aims to differentiate between stressed and non-stressed outputs in response to stimuli (e.g., questions posed), with high stress seen as an indication of deception.
