| Abstract: | In order to improve the speech recognition rate, an improved speech signal feature extraction algorithm is presented. The short-time energy and short-time zero-crossing rate of each frame signal based on MFCC parameters are increased in the algorithm ,which make the new parameters can provide a more accurate representation of speech signals. It is explained that the new feature parameters obtains high recognition rate through the simulation experiments. |
