                       This is a decision on appeal from the final rejection of claims 1 through 15, all of the claims pending         

               in the application.                                                                                                     

                       The invention pertains to time series signal recognition in general and to speech recognition in                

               particular.  Highly accurate recognition tests in quiet environments have been known but the recognition                

               rate is drastically reduced in noisy environments due to false pattern matching or failure of appropriate               

               word boundary detection.  While word spotting, or continuous pattern matching, has been used to alleviate               

               the problem, other problems have arisen.  As depicted in prior art Figure 1, the word boundary for a                    

               particular signal gets narrower as the noise level increases.  But, the speech recognition dictionary
