Searching for the best path that matches two time-series signals is the
main task for many researchers, because of its importance in these applications.
Dynamic Time-Warping (DTW) is one of the prominent techniques to accomplish this task, especially in
speech recognition systems. DTW is a cost minimisation matching
technique, in which a test signal is stretched or compressed according to a
reference template.
Although there are other advanced techniques in speech
recognition such as the hidden Markov modelling (HMM) and artificial neural network
(ANN) techniques, the DTW is widely used in the small-scale
embedded-speech recognition systems such as those embedded in cell phones.
The reason for this is owing to the simplicity of the hardware implementation of
the DTW engine, which makes it suitable for many mobile devices. Additionally,
the training procedure in DTW is very simple and fast, as compared with
the HMM and ANN rivals.
