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.

2. 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; 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 generating a corrected recognition output for a particular candidate correction having a score that satisfies a threshold value. - View Dependent Claims (3, 4, 5, 6, 7, 8)

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; 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 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)

16. 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 generating a corrected recognition output for a particular candidate correction having a score that satisfies a threshold value. - View Dependent Claims (17, 18, 19, 20)
