Query rewrite corrections
First Claim
Patent Images
1. A method 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, wherein determining that the recognition of the second voice query triggers the correction request includes parsing the second voice query to detect a correction prefix;
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.

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.

8. 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, wherein determining that the recognition of the second voice query triggers the correction request includes parsing the second voice query to detect a correction prefix; 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.

9. 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, wherein determining that the recognition of the second voice query triggers the correction request includes parsing the second voice query to detect a correction prefix; 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. - View Dependent Claims (10, 11, 12, 13, 14, 15)
