A new robust algorithm for isolated word recognition in low SNR environments is suggested . The algorithm, called WSP, is described here for left to right models with no skips. It is shown that the algorithm outperforms the conventional HMM in the SNR range of 5 to 20db, and the PMC algorithm in the range 0 to -9db.
