[Analysis of a control system for speech movements]

Analyzing the control quality in autonomic contour of articulation control system an account is made for the nonlinearities of the type of the zone ofunsensitivity, limitation and logarithmic response of the receptor. Regions of stablity and autooscillation frequency are determined. The role of recontrolling value is stated as a criterion of the control quality. It is suggested that the mechanisms of some stammering forms are concerned with the initiation of autooscillations in the articulation control system.
