Isolated Word Speech Rcogniton Based on HRSF and Improved DTW Algorithm

摘要

The paper introduces an isolated word speech recognition system in which the speech signal is acquired in real time, Half Raised-Sine function is applied to the MFCC parameters of the audio files, and improved DTW algorithm is implemented. Experimental results show that compared the conventional DTW with the improved DTW algorithm, the latter can obtain a better recognition rate and faster response time.
