ABSTRACT:
In a speech recognition system, dynamic time warp (DTW) calculations are reduced by use of a search strategy for an optimal non-linear search warp function path: signals predictive of the similarity are generated responsive to the preceding and current correspondence signals of the input word to reference warped words.
