Dynamic language model
First Claim
1. A method comprising:
- receiving a voice search query, the voice search query provided by a user to a user device;
determining a query context associated with the voice search query;
determining that the query context associated with the voice search query satisfies one or more criteria associated with a particular customized language model of a plurality of customized language models, wherein each customized language model includes one or more adjusted probabilities for respective word sequences of the language model, wherein the probabilities are adjusted with respect to corresponding word sequence probabilities in a base language model;
using the particular customized language model to generate a text search query from the voice search query; and
providing for display on the user device, one or more search results responsive to the text search query.

Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for speech recognition. One of the methods includes receiving a base language model for speech recognition including a first word sequence having a base probability value; receiving a voice search query associated with a query context; determining that a customized language model is to be used when the query context satisfies one or more criteria associated with the customized language model; obtaining the customized language model, the customized language model including the first word sequence having an adjusted probability value being the base probability value adjusted according to the query context; and converting the voice search query to a text search query based on one or more probabilities, each of the probabilities corresponding to a word sequence in a group of one or more word sequences, the group including the first word sequence having the adjusted probability value.
