A novel statistical language modeling method for continuous chinese speech recognition

摘要

Statistical language models can play an important role in continous speech recognition, but their performance is often unstable because of the training data sparsity. This paper proposes a statistical language modeling method, where the contribution of the language model is limited by acoustic matching result and the N-gram probability distribution is modified referring to the length of the silence duration between adjacent syllables. Besides, the paper proposes a powerful single state Hidden Morkov Model (HMM) to model various kinds of silence segments.
