What is computer voice stress analysis?
A pseudoscientific technology called voice stress analysis (VSA) and computer voice stress analysis (CVSA) purports to deduce deceit from stress signals in the voice. The CVSA uses a microphone to record human voice, and the technology is founded on the idea that the voice's non-verbal, low-frequency content contains data about the speaker's physiology and mental state. The technology, which is frequently used in investigative contexts, attempts to distinguish between stressful and non-stressed outputs in response to stimuli (such as questions given), with high stress being viewed as an indication of lying.
