| Abstract: | The technology of speech recognition has been widely used on non-contacting system,where one of the important research directions is the isolated-word speech recognition system based on the digital platform.Endpoint detection,MFCC feature parameters extraction and DTW pattern recognition for the voice signal have been implemented and simulated by Matlab.The results show that the system has strong instantaneity and high recognition rate. |
