Abstract: | The thesis mainly pays attention to the design of software and hardware circuits about the small glossary. The system takes DSP as hardware platform,adopting the MFCC as a characteristic parameter drawing algorithm,and taking the DTW as the distinguishing algorithm,having realized Speech recognition system's. The experiment bear fruit indicates that the average of voice recognition being lower than 90%,getting fine identification effect. |
