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.
为了比较汉语三音子模型在不同观测概率情况下的差异,本文构造了三种不同模型,及其训练和识别算法。
Experimental results show that phonetic classification based on the triphone can greatly improve system performance. The proposed method reduces the error rate by 28% compared with a baseline system.
