At Nuance Communications' Healthcare Partner Event in Berlin, web content editor Ian Bolland listened to Dr Nils Lenke's presentation'The I in AI', and spoke to the senior director, innovation management, Nuance, about how the'artificial intelligence' is built to allow its Dragon voice recognition system to work. For there to be artificial intelligence there must be human intelligence – which is probably one of the reasons why Dr Lenke feels that AI will be there to assist humans, and doesn't predict that robots will take over the world. In his presentation to delegates at Nuance Communications' Healthcare Partner Event in Berlin, Dr Lenke demonstrated the thinking behind building the intelligence that goes into building the artificial intelligence that powers the kind of speech recognition the company pioneers. A lot his talk focussed on'training data' to the point where human intelligence is rebuilt to make artificial intelligence as effective as possible, in the same way as with sound and photo recognition. Succinctly put, you can do mathematics with words.
