1. A computer-implemented method comprising: identifying one or more follow-up queries that are pre-associated with a term that matches a transcription of an initial utterance of a user, wherein the follow-up queries are (i) different than the term, and (ii) are pre-associated with the term based on query log data indicating that other users of a search engine have previously submitted the follow-up queries after submitting an initial query that includes the term; adjusting an initial language model to generate a modified language model, the modified language model specifying a respective probability associated with one or more of the follow-up queries that is increased with respect to the initial language model; receiving subsequent audio data corresponding to a subsequent utterance of the user; processing the subsequent audio data using the modified language model to generate a transcription of the subsequent utterance; and providing the transcription of the subsequent utterance for output to the user.
