Voice Stress Tests: What You Need to Know About Their Legal Definition
Definition & meaning
A voice stress test is an evaluation method that analyzes changes in a person's voice to determine whether they may be lying. The underlying theory suggests that when someone is not being truthful, their voice will exhibit specific physiological changes. A machine called a voice stress evaluator is used to monitor and interpret these changes. It is important to note that results from voice stress tests are typically not accepted as evidence in criminal or civil court proceedings.
