Query rewrite corrections
First Claim
Patent Images
1. A method comprising:
- receiving a first voice query from a user device;
generating a first recognition output;
receiving a second voice query;
determining, from a recognition of the second voice query, that the second voice query triggers a correction request;
using the first recognition output and the second recognition to determine a plurality of candidate corrections including determining a misrecognition portion of the first recognition output and substituting the misrecognition portion with one or more candidate n-grams to form one or more candidate corrections;
scoring each candidate correction; and
for a particular candidate correction having a score that satisfies a threshold value, using the particular candidate correction as an input search query to a search engine.

Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for natural language processing. One of the methods includes receiving a first voice query; generating a first recognition output; receiving a second voice query; determining from a recognition of the second voice query that the second voice query triggers a correction request; using the first recognition output and the second recognition to determine a plurality of candidate corrections; scoring each candidate correction; and generating a corrected recognition output for a particular candidate correction having a score that satisfies a threshold value.

10. A system comprising:
-
a user device; and one or more computers configured to interact with the user device and to perform operations comprising; receiving a first voice query from the user device; generating a first recognition output; receiving a second voice query from the user device; determining from a recognition of the second voice query that the second voice query triggers a correction request; using the first recognition output and the second recognition to determine a plurality of candidate corrections including determining a misrecognition portion of the first recognition output and substituting the misrecognition portion with one or more candidate n-grams to form a candidate correction; scoring each candidate correction; and for a particular candidate correction having a score that satisfies a threshold value, using the particular candidate correction as an input search query to a search engine. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. One or more non-transitory computer-readable storage media encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:
-
receiving a first voice query; generating a first recognition output; receiving a second voice query; determining from a recognition of the second voice query that the second voice query triggers a correction request; using the first recognition output and the second recognition to determine a plurality of candidate corrections including determining a misrecognition portion of the first recognition output and substituting the misrecognition portion with one or more candidate n-grams to form a candidate correction; scoring each candidate correction; and for a particular candidate correction having a score that satisfies a threshold value, using the particular candidate correction as an input search query to a search engine.
