SUMMARY:Speech as a dynamical system\, Chaos & Complex Systems Seminar
 \, Ben Parrell\, UW Department of Communication Sciences and Disorders
DESCRIPTION:The act of speaking is one of the most complex motor behav
 iors humans produce: a set of over 100 muscles must be precisely coord
 inated in space and time to produce rapid movements (50-300 ms) at a h
 igh rate (roughly 40 unique sounds per second). How can we control suc
 h a complex system with enough precision to produce intelligible speec
 h? This talk will present the view that speech is a hierarchical dynam
 ical system\, with control needed only at a high-level (of speech goal
 s or tasks) rather than a system where all muscle activations are cont
 rolled centrally. I will explain how this approach can explain speech 
 phenomena in various languages\, and show a preliminary sketch of how 
 such a system could be instantiated in the brain.
