Hearing is like seeing for our brains and for machines

Nils Lenke is the senior director of corporate research at Nuance Communications. There is an array of neural net machine learning approaches that are simply more than just "deep." In a time when neural networks are increasingly popular for advancing voice technologies and AI, it's interesting that many of the current approaches were originally developed for image or video processing. One of those methods, convolutional neural networks (CNNs), makes it easy to see why image-processing neural nets are strikingly similar to the way our brains process audio stimuli. CNNs, therefore, nicely illuminate that our audio and visual processes are connected in more ways than one.
