1. A system comprising: a computer-readable memory storing executable instructions; and one or more processors in communication with the computer-readable memory, wherein the one or more processors are programmed by the executable instructions to at least: obtain audio data regarding an utterance of a user; initiate speech recognition on the audio data using a grammar of a composite language model, the composite language model comprising the grammar and an n-gram model, wherein the composite language model comprises scores that bias speech recognition performed using the composite language model to use the grammar over the n-gram model, and wherein a first state of the grammar links to a first state of the n-gram model and to a second state of the grammar; generate at least a first portion of automatic speech recognition results using a portion of the grammar up to at least the first state of the grammar; determine a first score using (1) acoustic information derived from the audio data and (2) a first weight associated with a link from the first state of the grammar to the second state of the grammar; determine a second score using (1) acoustic information derived from the audio data and (2) a second weight associated with a link from the first state of the grammar to the first state of the n-gram model; if the first score is greater than the second score, continue speech recognition on the audio data using the grammar by generating a second portion of automatic speech recognition results using the second state of the grammar, wherein the second portion of automatic speech recognition results is based at least in part on the first score; if the second score is greater than the first score, continue speech recognition on the audio data using n-gram model by generating the second portion of automatic speech recognition results using the first state of the n-gram model, wherein the second portion of automatic speech recognition results is based at least in part on the second score; and generate automatic speech recognition results based at least on the first portion of automatic speech recognition results and the second portion of automatic speech recognition results.
2. The system of claim 1 wherein a third score is associated with a link between a third state of the grammar and a second state of the n-gram model, and wherein the third score is different than the second score associated with the link between the first state of the grammar and the first state of the n-gram model.
