In the light of the poor ability to describe the long-distance information of a sentence and the serious data sparse phenomenon of the mainstream n-gram language model, the RNN modeling method which can capture the inherent rules of natural language better and overcome the inadequacy of n-gram model was firstly used for Chinese language. To further improve the model performance, a model combination method was introduced so that RNN and the n-gram model can be merged together respectively. This

The experiment results show that the RNN language model has a great superiority with better modeling performance. Meanwhile, with the combination of the models, the system recognition rate increases effectively on the task of Chinese telephone speech recognition.
