In the precondition of all rare triphones are selected out of raw materials, we tried to balance the triphone.
在保证稀有三音子全部被选择出的前提条件下，使三音子尽量平衡。
2
Triphone models can distinguish the same digit under different contexts, so they can markedly improve the recognition rate.
三音子模型将不同上下文的同一个数字区分开来，明显提高了识别率。

To compare triphone models under different observation densities in Chinese language, three models and their respective algorithms of training and recognizing are constructed.
