Abstract :
A model of a neural network of the auditory system is presented; it is based on the representation of the temporal activity of N fibers by a random field defined on a finite set. Our simulations show the behavior of the network in response to different stimuli; we investigate the duration of the transient times of the output random field and establish the link between these durations and a context effect. The results are consistent with the characteristics of a speech signal, and we could compare some of them to typical perceptive measures made on stop consonnants.
