ABSTRACT:
A euclidean distance between an input pattern and a reference pattern is elementwise determined, to sequentially calculate a set of cumulative values thereof, which is stored in a work memory for use in a current recurrence calculation and in a cumulative data memory for use in a decision for a speech recognition. The recurrence calculation is executed on one of division blocks obtained by collecting input frames and reference frames. Stored data in the work memory are shifted every block for a subsequent recurrence calculation.
