14. The feature compensation method of claim 13 , wherein the generation of the compensated speech features comprises eliminating the estimated noise features of the corrupt speech features using a statistical model of the training speech features, the estimated noise features, the extracted corrupt speech features, and the HMM state probabilities.
13. The feature compensation method of claim 8 , wherein the calculation of the correlation comprises obtaining a statistic model with a hidden Markov model (HMM) structure of training speech features from training speech signals that consist of two or more frames, decoding the training speech features into a HMM, and calculating HMM state probabilities.
