UFS 211: ACADEMIC READING AND WRITING

TASK 9: SUMMARY

A new version of lie detector that works by voice recognition and can be used without a subject's knowledge has been introduced in Britain. The device is used by private industry for pre-employment screening, investigating thefts, and even periodic staff checks. The device normally recognize voice tones by analysing the infrasonic FM component so that it is possible to pick out a word or phrases that caused stress. In the US, the device is used for pre-employment interviews. They only tape record the interview and analyse it to show the honesty of the employee. The problem is its primary application would be in situation where people may not object because it can also be used to provoke a personal issues unrelated to jobs such as political affiliation.
