The HCLG graph is the recognition network which defines the paths that the beam-search HMM decoder will be exploring. This graph contains costs that can be altered ... Web引言—语音识别ASR. 参考博客. 在基于GMM-HMM的传统语音识别里，比音素（phone）更小的单位是状态（state）。一般每个音素由三个状态组成，特殊的是静音（SIL）由五个状态组成。这里所说的状态就是指HMM里的隐藏的状态，而每帧数据就是指HMM里的观测值。

WebWe used Kaldi [5] to train recognizers for several ASR tasks. To model the accuracy and bandwidth of our hardware-oriented algorithm changes, we constructed a separate ASR decoder in C++ and performed comparisons with a speaker-independent recognizer on the WSJ [6] dev93 task. The recog-nizer’s pruned trigram LM (bd tgpr in the Kaldi recipe) has WebI followed the instruction on extending ASpIRE model with custom dictionary and language model.
