1. A method to correct for packet loss in an audio signal in automatic speech recognition systems comprising rescoring of phoneme probability calculations for a section of the audio signal, comprising the steps of:
accumulating probabilities for a given word in a lexicon using the highest scoring tokens for every frame of the audio signal;
determining when the probabilities for the given word are statistically significant;
reporting matches when the probabilities are statistically significant;
normalizing values of probabilities that are not statistically significant by replacing values for section of the audio signal comprising packet loss; and
rescoring the probabilities for the given word.
