Abstract

Given a method for evaluating the acoustic match between a word and a segment of an acoustic signal, the invention determines in general how to attach acoustic scores to clusters of words. This produces the method for implementing a search tree in the process of selecting words that fit well to a given acoustic signal. This method is applied to the polling fast match.
