A new form of lie
detector called Psychological Stress Analyzer has been introduced in Britain. This
new technology works just as other type of detector but contain one component
that is caused by vibration of the muscles inside the mouth and throat. It
added a clearly noticeable frequency modulated component to the voice. But PSE
can only show stress not dishonesty and has it own standard in reporting. In
cons the wide use of this device for pre-employment interview is extremely
disquieting even though it is not foolproof. This detector should be prevented
before they become wide spread.
