Abstract
A method for fast match processing, comprising two stages, a pre-processing stage and an on-line stage. The pre-processing stage comprises the steps of computing an a-priori probability of occurrence for each word from an acoustic vocabulary; deriving a penalty score for each word from said acoustic vocabulary based on each words a-priori probability of occurrence in an input text. The on-line stage operates on an input text stream, comprising the steps of, computing a path score for each word from said input text; combining the computed path score with the derived penalty score to form a combined score and testing the combined score against a threshold to determine top ranking candidate words.
