One-Step Repair of Misrecognized Recognition Strings
First Claim
1. A method for use in automatic speech recognition comprising:
- recognizing a user input as a correction hypothesis containing a plurality of recognition elements;
performing a non-deterministic alignment of at least a portion of the correction hypothesis with an earlier recognition hypothesis containing a plurality of recognition elements such that the recognition elements in the aligned portion of the correction hypothesis are determined to most likely correspond to a range of recognition elements in the earlier recognition hypothesis;
replacing the elements in the range of recognition elements in the earlier recognition hypothesis with the recognition elements in the aligned portion of the correction hypothesis.

Abstract
A method for use in automatic speech recognition corrects erroneous recognition elements within a recognition hypothesis. A user input is recognized as a correction hypothesis which contains various recognition elements. A non-deterministic alignment is performed to align at least a portion of the correction hypothesis with an earlier recognition hypothesis which also contains various recognition elements such that the recognition elements in the aligned portion of the correction hypothesis are determined to most likely, correspond to a range of recognition elements in the earlier recognition hypotheses. The recognition elements in the range of recognition elements in the earlier recognition hypothesis are replaced with the recognition elements in the aligned portion of the correction hypothesis.
