Councils across Britain are to start using lie detectors to catch benefits cheats claiming money they are not entitled to. It is hoped the 'voice-risk analyser' system, which monitors speech patterns, could save taxpayers tens of millions of pounds. The device looks for changes in the sound of a claimant's voice, a sign they might not telling the truth. Officers using then are able to ask for further evidence to support any claims highlighted as being suspicious. 15 councils currently have access to the machines which are expected to be rolled out nationally. Seems pretty heavy. It'll be finger up the bum next!
