A Lie detector has been introduced in Britain. The various ways in which this machine can be used is it works by voice analysis and without a subject's knowledge. Besides, to the normally understood voice generation mechanisms. In addition, Dektor emphasises that the device shows only stress, not dishonesty. Moreover, the devices is used for pre-employment interviews. The objections to its use is there seems no law to prevent it use.
