APPARATUS FOR PATTERN RECOGNITION A temporal sequence of signal vectors X (e.g. generated from a speech signal) is supplied in parallel to elements 101 in an array each of which (after training of the array) provide an output ? indicating the vector's similarity to a reference vector. Persistence is (115) built into the elements so that signals forming a "trajectory" within the array, corresponding to an input sequence are simultaneously available for recognition (unit 110 or, preferably by a further such array). Arrays may be cascaded to allow for longer sequences. |
