Ex parte TAKEBAYASHI et al. - Page 5

               Appeal No. 1997-4121                                                                                                    
               Application No. 08/427,272                                                                                              

               Rather, it is the combination of the word spotting scheme and the specific learning scheme which                        

               distinguishes over the applied prior art.                                                                               

                       While word spotting was well known, the references to Takebayashi and Bahler are alleged by                     

               appellants to be deficient in showing any word spotting schemes.  Since word spotting is a continuous                   

               pattern matching method in which the word boundary is taken to be not fixed but flexible (see the definition            

               at lines 3-4 of page 2 of the specification), it does appear that neither Takebayashi nor Bahler discloses              

               such a method.  Takebayashi uses a recognition means which detects starting and ending points, thus fixing              

               the word boundary.  While Bahler does disclose the recognition of keywords in a “continuous” audio                      

               signal, and would thus appear to be indicative of a word boundary which is not fixed, further review of the             

               reference would appear to indicate otherwise.  For example, the reference discloses a plurality of                      

               templates representing silence, or nonspeech, signals, which would appear to indicate that these templates              

               would set some kind of boundary around a spoken word.  In any event, appellants submit, as evidence, a                  

               declaration under 37 CFR 1.132, from Mr. Hidenori Shinoda, a clearly skilled artisan.  Mr. Shinoda                      

               explains that the concatenation technique of Bahler “is a technique for connecting two or more specific                 

               word templates in order to detect word sequences..., which is part of the syntax control used in                        

               determining beginning and ending boundaries of unknown keywords in Bahler.”  Mr. Shinoda explains,                      

               further, that this “technique is totally unrelated to whether the recognition is ‘word spotting’ or not, because        

               the difference between ‘word spotting’ and ‘non-word spotting’ is not a matter of how word templates are
