Abstract
In a speech recognition device including a similarity calculator for calculating a usual similarity as a provisional similarity between an input pattern and prepared reference patterns, a calculating arrangement calculates a reference similarity between the input pattern and produced reference patterns. A correcting unit corrects the provisional similarity by the reference similarity into a corrected similarity. As usual, the similarity may be a dissimilarity. The prepared reference patterns may be memorized in the calcultor or be given by concatenations of primary recognition units. Preferably, the produced reference patterns are concatenations of secondary recognition units memorized in a memory.
