Abstract :
Earlier we offered the theory of speech rhythm with Feigenbaum´s scenario for route to chaos. Now we use the simple model of control parameter dynamics representing ≪inhibition≫ in neural system. This dynamics performs some limit cycle in coordinates: ≪inhibition≫ and ≪excitation. Different cycle positions in both chaos zone and bifurcation zones explains two different forms of the stutterers´ speech as well as the existence of mixed form of adolescent age.
