this is an example of the successful use of 'Voice Risk Analysis' from a fraud and error supplement to the latest issue of the DWP's HB Direct ....

'Whilst on hold another customer was heard to say: 'Quick, quick it's the Housing. They are checking my claim. They know something’s wrong, what shall I say?' The claim was referred for a follow-up call. When put on hold again the customer said to his 'landlord': 'I didn’t tell them that we're together, I just told them we're friends…' This case has now been passed to the Investigations Unit.'

I'm sure that the equipment would pick up the words "quick" coupled with "housing benefit" and know something was odd.
