These methods have almost ex- clusively worked within the noisy channel paradigm, where the syntactic language model has the task of modeling ... predominant approach within language model- ing for speech recognition has been to use an n- gram language model, within the “source-channel” or “noisy-channel” paradigm....

Each syntactic language model state is a random variable ... parsing for language modeling, but do not use this language model in a translation system. Our work, in contrast to the above approaches, explores the use of incremental syn...
