摘要
就语音识别中所用到的语言模型进行了详细阐述,对语言模型中涉及到的N-gram模型进行了解析,以及对在训练语言模型过程中遇到的零概率问题相应的平滑处理方法进行了讲解。利用N-gram训练的语言模型运用到语音识别中,取得了相当好的效果。
This paper described language model in the speech recognition process in detail,analyzed Ngram which was associated with language model,and explained the corresponding smoothing method which could solve the zero probability problem in the process of training the language model. By using trained language model that was trained by N-gram,applied to speech recognition,which achieved very good results.
