Adapting enhanced acoustic models
First Claim
1. A computer-implemented method comprising:
- receiving a particular voice query submitted by a user;
receiving feedback information from a user after the user is presented with a set of search results that was generated in response to a search query that included a transcription of the particular voice query;
generating a score indicative of a probability that the transcription of the voice query is correct based at least on the feedback information;
determining that the score that is generated based at least on the feedback information satisfies a threshold; and
in response to determining that the score that is generated based at least on the feedback information satisfies the threshold, adapting an acoustic model using the particular voice query.

Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enhancing speech recognition accuracy. In one aspect, a method includes receiving voice queries, obtaining, for one or more of the voice queries, feedback information that references an action taken by a user that submitted the voice query after reviewing a result of the voice query, generating, for the one or more voice queries, a posterior recognition confidence measure that reflects a probability that the voice query was correctly recognized, wherein the posterior recognition confidence measure is generated based at least on the feedback information for the voice query, selecting a subset of the one or more voice queries based on the posterior recognition confidence measures, and adapting an acoustic model using the subset of the voice queries.

8. A system comprising:
-
one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising; receiving a particular voice query submitted by a user; receiving feedback information from a user after the user is presented with a set of search results that was generated in response to a search query that included a transcription of the particular voice query; generating a score indicative of a probability that the transcription of the voice query is correct based at least on the feedback information; determining that the score that is generated based at least on the feedback information satisfies a threshold; and in response to determining that the score that is generated based at least on the feedback information satisfies the threshold, adapting an acoustic model using the particular voice query. - View Dependent Claims (9, 10, 11, 12, 13)

14. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
-
receiving a particular voice query submitted by a user; receiving feedback information from a user after the user is presented with a set of search results that was generated in response to a search query that included a transcription of the particular voice query; generating a score indicative of a probability that the transcription of the voice query is correct based at least on the feedback information; determining that the score that is generated based at least on the feedback information satisfies a threshold; and in response to determining that the score that is generated based at least on the feedback information satisfies the threshold, adapting an acoustic model using the particular voice query. - View Dependent Claims (15, 16, 17, 18, 19)
