Goerge...
George is a 'chat robot'. A new brand of robot who has the capability to learn languages, in fact, he knows over forty. George has animations as well, he can grin quite freakishly, and drum his fingers impatiently.
"When users enter a line of conversation, George responds by "remembering" how past conversational partners answered when he said something similar to them."
"Unlike many other conversational programmes, it's not trying to merely be logical. It's trying to form relationships, to be entertaining, and it can seem rather alive." (Mr. Carpenter, creator of George speaking)
"George can also now speak to users and understand their responses. Mr Carpenter and Mr Child hope that spoken conversation will improve his responses, because people speak more naturally than they type."
