For those of you old enough to remember the Yes / No Interlude in the television series Take Your Pick hosted by Des O’Connor or even those of you old enough to remember Michael Miles in the original here is a warning which will bring back some memories. Should you receive a phone call asking you a simple question such as Is that Mr Jones or Is that telephone number 123456 to which you answer ‘ yes’, then that answer can be recorded and used to validate bank withdrawals, credit card payments etc. as voice recognition becomes more prevalent. So answers should not be yes or no but That’s correct, Agreed etc.
