Subject: Voice and sound processing in the brain
Question: Hello,

How does the brain recognize whether a signal is a voice (and belongs to a language system) or it is a noise? From what age can a young baby gain this ability?

And finally could you please introduce me some books or sources on these topics for additional information?

Thanks

Reply: Rhythm and other prosodic cues seem to play a core role in speech perception. See e.g. this article, ‘Language discrimination by newborns: toward an understanding of the role of rhythm’, which deals with infant discrimination among different languages:
<a href='http://www.ncbi.nlm.nih.gov/pubmed/9627414' target='_blank'>http://www.ncbi.nlm.nih.gov/pubmed/9627414</a>; ,

and the chapters collected in this book, _Perceptual development: visual, auditory, and speech perception in infancy_:
<a href='http://www.routledge.com/books/details/9780863778513/' target='_blank'>http://www.routledge.com/books/details/9780863778513/</a>;

Both references are rather dated, but a search for current work by the authors/editors, for example on Google Scholar, may help.
