Cerebral Processing of Voice Information: From Monkeys to Deep Learning

—————————

How do we extract and process the treasure-trove of information in voices? Experiments involving techniques ranging from monkey neuroimaging to deep learning provide an increasingly detailed picture of the ‘vocal brain’ and its evolution in primates. Results suggest an organization in several ‘voice patches’ analogous to that of the face patch system.
