Task 9

Summarize

A new form of lie detector that works by voice analysis and which can be used without a subject’s knowledge has been introduce in Britain. The Dektor psychological stress analyzer (PSE) is used by private industry for pre-employment screening, investigating thefts, and even periodic staff checks. It can understood voice generation mechanisms-vibrations of the vocal  chords and resonance of inside the head-there is a third component caused by vibration of the muscle inside the mouth and the throat. Other than that, it Dektor  emphasizes than the device shows only stress, not dishonesty. In the US,  the device is used for pre-employment interview, with question such as ‘Have you used marihuana?’ and for monthly checks with branch managers, asking question like ’Do you suspect any present employees of cheating the company?’-which at least prevent a manager from setting his own pace to investigate possibly suspicious behavior. The objection to its use are than most serious problem is that its primary application will be in situation where people may not object-such as pre-employment interview. The PSE can be used without the subject even knowing; its inventors analyzed the televised Watergate hearing and told the press who they thought was lying.
