Apparatus that solves the problem of pattern recognition in a temporal signal that is subject to distortions and time warp. The arrangement embodying the invention comprises a neural network, an input interconnection network, and a plurality of signal modification circuits. A plurality of input leads delivers a preselected characteristic stimulus to associated signal modification units, and in response to an applied stimulus, each signal modification unit develops a plurality of output signals that begins at the time of stimulus application, rises to a peak, and decays thereafter. The mean time delay of each output (time to reach the peak) is different for each of the modification unit output signals. The outputs of the signal modification units are applied to the input interconnection unit wherein connections are made in accordance with the sequences that are to be recognized.

A system for recognizing at least one pattern comprising: a plurality of stretchable delay means, each responsive to an applied input signal and each developing a set of different delayed signals, with said different delayed signals in each set differing from each other in delay and duration; an interconnection network for selectively connecting said delayed signals to a plurality of outputs; and a network responsive to said plurality of outputs for developing a preselected output signal indicative of recognition of said pattern.
