Abstract
A speech recognition approach that involves forming a series of segments associated with a spoken utterance. Each segment has a time interval within the utterance, and scores characterizing the degree of match of the utterance in that time interval with a set of subword units. Based on the series of segments, the approach includes determining a set of word sequences hypotheses associated with the utterance and then computing scores for the set of word sequence hypotheses using a second set of subword units to represent words in the word sequence hypotheses.
