A Research on improving DTW in speech recognition
Guoshun Huang · Microcomputer Information · 2010
Dynamic Time Warping is a kind of classic programming in speech recognition system. The DTW algorithm is simple and effective. For the questions of great computation and storage,the paper puts forward improving the computation of cumulative distance and relaxing the alignment of vertices. The experiments results show that the improved DTW algorithm gets better performance in speech recognition of single word.
