Abstract
This speech recognition system uses a converted-spectrum for comparison of unknown and prestored reference signals. The comparison distance is modified by a weighting factor W to emphasize differences. A straight line approximation of the short term spectrum provides a datum against which the original spectrum is differenced to provide the converted spectrum, and provide deviation signs which are used to modify an initial prestored weighting factor P to form W.
