Detecting potential significant errors in speech recognition results
First Claim
1. A method comprising:
- evaluating two or more results of a recognition, by an automatic speech recognition (ASR) system on a speech input, using at least one criterion that differs from criteria used by the ASR system in determining the two or more results, wherein the two or more results were identified by the ASR system as likely to be accurate recognition results for the speech input and comprise a first recognition result identified by the ASR system as most likely to be a correct recognition result for the speech input and at least one alternative recognition result identified by the ASR system as a potential recognition result for the speech input; and
in response to determining that the at least one criterion is met by the two or more results, triggering presentation, via a user interface, of an alert concerning one of the two or more results.

Abstract
In some embodiments, recognition results produced by a speech processing system (which may include two or more recognition results, including a top recognition result and one or more alternative recognition results) based on an analysis of a speech input, are evaluated for indications of potential errors. In some embodiments, the indications of potential errors may include discrepancies between recognition results that are meaningful for a domain, such as medically-meaningful discrepancies. The evaluation of the recognition results may be carried out using any suitable criteria, including one or more criteria that differ from criteria used by an ASR system in determining the top recognition result and the alternative recognition results from the speech input. In some embodiments, a recognition result may additionally or alternatively be processed to determine whether the recognition result includes a word or phrase that is unlikely to appear in a domain to which speech input relates.
