How to spot a lie. Michael Rosen vs Richard Sheridan, managing director of Teceris Validation Services, part of the Capita Group

 

The BBC Radio 4 program “Word of Mouth” broadcast 12th January 2010 and presented by Michael Rosen investigated lying. It’s strap line was “Does our voice change when we are trying to deceive?”.

Part of the program included an interview between Michael Rosen and Richard Sheridan, managing director of Teceris Validation Services, part of the Capita Group.

Teceris Validation Services provide software which Teceris claims analyses real-time telephone conversations and alerts the operator when a callers voice is, according to it’s analysis, exhibiting signs that there is a risk that the caller is lying. When this happens the operator, but not the caller, hears a tone on their headset.

This voice analysis software is already in use by some councils in the UK and according to Capita it’s use looks set to expand. http://www.capita.co.uk/Pages/VoiceRiskAnalysis.aspx

Lie detector tests are famously controversial because to date none of them, including the polygraph test used in the USA, have been able to be backed up by independent research.

In this audio clip from the BBC’s Radio 4 “Word of Mouth” the first voice that you hear is that of Michael Rosen the second is that of Richard Sheridan, managing director of Teceris Validation Services.
