The sound of me

How often do you ring your bank and forget the special dates, places or names needed just to get through security? Apparently, it takes us 45 seconds on average just to confirm who we are. Now that might not seem very long, but if you're a global bank like Citi receiving 35 million calls a year in Asia alone, that adds up to 437,500 hours of staff time a year. But by using computers to identify our voices, this authentication process can be cut to 15 seconds on average, saving the bank pots of cash and us lots of hassle. Citi has just begun rolling out this kind of voice biometrics authentication for its 15 million Asian banking customers, starting in Taiwan, Australia, Hong Kong and Singapore.
