Data smoothing is the key technology of statistical language modeling,It not only can improve the performance of language modeling,it Can also improve speech recognition and Application areas such as language identification system recognition rate.Different data smoothing method should be at the contrast between the different scale of operation on the training set.A variety of smoothing algorithms,To Good-Turing estimate,linear interpolation smoothing,Katz's back-off-type is most typical and commonly used smoothing.In this paper,various methods of data smoothing empirical comparison,and discussed the impact of these data smoothing method performance of relevant factors.
