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
