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.

First claim

What is claimed is:

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 se…
