Virtual Assistant Will Screen Your Phone Calls to Block Spammers
Georgia Institute of Technology researchers have developed a virtual assistant that screens phone calls to block robocallers.
Numbers not on a phone's contact list are diverted to the assistant, which asks the caller to state the recipient's name; if the caller responds, the assistant interrupts with, "Sorry I didn't get that. Can you please say who you are trying to reach again?" If the caller is live, they will stop speaking, and the assistant will pass on the call and a transcribed name through an application.
The system blocked 100% of 8,000 recorded robocalls and 97.8% of 21 human callers who engaged with the assistant but occasionally used the incorrect name.
"It's like a spam filter that checks that the sender has at least minimal knowledge about the addressee and is flexible enough to produce that knowledge on request," says University of Potsdam Professor David Schlangen.
