Description	The paper presents a method for incorporation of regular grammars into n-gram language models. Such composite model then benefits from both language modeling formalisms - a grammar yields robust probability estimates for well-defined phrases with fixed structure whereas the n-gram provides better coverage of casual speech. Moreover, the grammar allows adding new words to the phrase pattern while taking advantage of the existing structural (context) information. The proposed method for grammar incorporation allows the use of combined models in our in-house real-time decoder which is designed to work only with standard n-gram language model. The performance of the combined model was tested in the dictation task where a simple grammar was designed for date entries. A statistically significant improvement of WER was achieved.
