Abstract: A novel set efficient algorithms is introduced. With the study of hardware platform of personal computer, cache optimization, changing Mahalanobis distance to parallel inner product and utilizing the single instruction multiple data stream instruction set are presented. With these methods, the speed of recognition of both speech recognition and speaker identification increase about 3 times.
