Abstract
This paper describes 2 efficiency enhancements for speaker-independent connected spoken word spotting. The first enhancement, LESS COST, uses phoneme concatenation to reduce the cost of computing the local distance between each reference and input pattern point. The second enhancement, Coarse DP refinement, reduces the cost of dynamic time warping for only a small error rate penalty. An experiment confirmed these techniques.
