Abstract :
Neural mechanisms for the detection of articulatory-acoustic events, which are based on a model of the peripheral auditory system, are studied. Several specialized neural networks, composed of `on´ neurons and large-scale spatial integration mechanisms, are proposed for further processing the firing pattern of the auditory nerve. It is shown that although they are very simple in structure and preliminary in nature, these channels are physiologically plausible and powerful enough for the detection of most of the articulatory-acoustic events considered
