The Cambridge Handbook of Communication Disorders examines the full range of developmental and acquired communication disorders and provides the most up-to-date and comprehensive guide to the epidemiology, aetiology and clinical features of these disorders.
Speech is the principal supporting medium of language. In this book
Pierre-Yves Oudeyer considers how spoken language first emerged. He
presents an original and integrated view of the interactions between
self-organization and natural selection, reformulates questions about the
origins of speech, and puts forward what at first sight appears to be a
startling proposal - that speech can be spontaneously generated by the
coupling of evolutionarily simple neural structures connecting perception
He explores this hypothesis by constructing a computational system to model
the effects of linking auditory and vocal motor neural nets. He shows that
a population of agents which used holistic and unarticulated vocalizations
at the outset are inexorably led to a state in which their vocalizations
have become discrete, combinatorial, and categorized in the same way by all
group members. Furthermore, the simple syntactic rules that have emerged to
regulate the combinations of sounds exhibit the fundamental properties of
modern human speech systems.
