The Research of DTW Algorithm Based on Non-voice Type Signal
Abstract:In the field of speech recognition, dynamic warping algorithm has been widely used, while in non-voice type signal field of pattern recognition are discussing now insufficient. This paper describes the basic components dtw algorithm, especially the pre-processing of the characteristic value extraction. From the macro to solve a non-voice-class signal applications, the bottleneck theory, while full use of this robustness of the algorithm is a good feature to solve the signal problem of time stretching.
Keywords: dtw algorithm eigenvalue extraction robustness
