傳統演算法
1） BerkeleyLM 是用java寫的，號稱跟KenLM差不多，記憶體比srilm小
https://github.com/adampauls/berkeleylm
2）MITLM (The MIT Language Modeling toolkit) 引數優化做的比較好
https://code.google.com/p/mitlm/ or https://github.com/mitlm/mitlm
3）SRILM（The SRI language modeling toolkit) 老牌語言模型工具，SRI（Stanford Research Institute）開發，c++版本
http://www.speech.sri.com/projects/srilm/
另外Maximum entropy (MaxEnt) language models is supported in the SRILM toolkit

4）IRSTLM (IRST language modeling toolkit) 義大利TrentoFBK-IRST實驗室開發處理較大規模的訓練資料，integrated into Moses 。
IRSTLM在訓練語言模型時採用了劃分詞典分塊訓練快速合併的方式,從而在訓練大規模語料時取得了優異的效能。
IRSTLM 訓練語言模型時分以下 5 步:
- a)在訓練語料上統計帶詞頻詞彙表；
- b)按照詞頻均衡的原則將詞彙表劃分為若干個子詞彙表；
- c)對各個子詞彙表統計 n-gram,這些 n-gram 必須以詞彙表中的詞彙開頭；
- d)根據第四步的統計結果,建立多個子語言模型；
- e)把所有的子語言模型融合成最終語言模型

5）KenLM (Kenneth Heafield's language model toolkit) 最大特點是速度快、佔用記憶體少。號稱比SRILM要好一些，支援單機大資料的訓練,包括c++和python兩個介面

6）Bigfatlm Provides Hadoop training of Kneser-ney language models, written in Java
https://github.com/jhclark/bigfatlm
7）Kylm (Kyoto Language Modeling Toolkit) written in Java,Output in WFST format for use with WFST decoders
http://www.phontron.com/kylm/ or https://github.com/neubig/kylm
8) OpenGrm Language modelling toolkit for use with OpenFst, makes and modifies n-gram language models encoded as weighted finite-state transducers (FSTs)

深度學習
1）RNNLM(Recurrent neural network language model toolkit)

2）BRNNLM (Bayesian recurrent neural network for language model)

3）RWTHLM (RWTH Aachen University Neural Network Language Modeling Toolkit, includes feedforward, recurrent, and long short-term memory neural networks)
http://www-i6.informatik.rwth-aachen.de/web/Software/rwthlm.php
4）Character-Aware Neural Language Models，employs a convolutional neural network (CNN)over characters to use as inputs into an long short-term memory (LSTM)recurrent neural network language model (RNN-LM)
