12. A system for providing a query history expansion, the system comprising: a memory storage; and a processing unit coupled to the memory storage, wherein the processing unit is operable to: receive a plurality of previous queries associated with a user, create an adapted language model that includes interpolating previous queries associated with the user and previous queries associated with a plurality of other users that share at least one common characteristic, wherein the previous queries of the plurality of other users is identified based on queries from the plurality of other users that contain click URLs as the user's previous queries and identified based on queries of the plurality of other users that are within a threshold distance of the user's previous queries, receive a spoken query from the user, convert the spoken query into a text string and apply the created adapted language model to generate at least one result for the converted spoken query, and transmit the at least one result of the converted spoken query to the user.
