Abstract

A method of path-limitation is proposed for the efficient DP matching of spoken words. Results of a preliminary recognition experiment show that this method can reduce the recognition errors as well. A method for effective speaker normalization is proposed. This method is based on the transformation of the relative positions of the five vowels of a given speaker in the parameter space. As a result of transformation, the dimension of the parameter space is reduced by a factor of four, yielding a great advantage in the computation time for matching. A study on the realization of a spoken-word recognition device using systolic array processors is described. A cyclic configuration that permits real-time matching of 600 templates with a single LSI chip is proposed
