Abstract: This paper expatiates the basic principles of the LPC characteristic coefficients and the DTW pattern matching, then implements the Durbin algorithm for the LPC and an efficient algorithm for the DTW. Basing on the requirement o f English study, it designs and implements a speech pattern comparison applicati on.
