Abstract

The "hidden" recurrent structure is established of temporal organization of acoustic speech signal. Such "hidden" recurrence can be revealed only due to experimentally established existence of two qualitatively different modes in the temporal organization of stutterers' speech. A theoretical model of speech generation is developed with a logistical property of "hidden" parameters in order to explain this phenomenon. This model is stated in terms of chaotic dynamics and is based on the neurophysiological striopallidal mechanisms which are realized under conditions of polysensory afferent impulsation. The effects of speech memory and actualization of its traces are explained on the basis of our earlier concept of perception of the rhythmical speech sequence. This concept allowed us to discuss the experimentally observed phenomenon of inhibitory modulation under conditions of both ipsi- and contralateral global negative feedback.
