摘要 本系统基于反馈调节HMM改进模型方法,依据HMM数学模型原理,找到这种模型的内在缺陷,提出一种反馈学习的修正原理,通过实验找出最优数据,正确反映汉语语音的数学模型,大大提高语音识别率。 Based on the feedback adjust,the intrinsic defects of the HMM mathematical model are found and a modified principle of feedback study is suggested. Then the optimal data are obtained experimentally. The resultant mathematical model can correctly reflect the pronunciation of Chinese language and the automatic speech recognition efficiency is greatly improved.
