| 摘 要： | 介绍了利用三音子模型和基频信息提高汉语连续数字串的识别率。在汉语连续数字串识别中“8”和“2”是容易混淆的数字,而“9”和“6”在识别时会在末尾插入一个“5”而变成“95”和“65”。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。基频反映了声调的变化,将它们作为后处理进一步降低了错误率。

| Abstract: | In this paper,triphone models and pitch information are incorporated in the recognition of Chinese connected digits. In Chinese connected digits recognition,"8"and"2"are one of the confusable pairs of digits.Moreover,"9" and "6" are easily recognized as "95" and "65". Triphone models can distinguish the same digit under different contexts, so they can markedly improve the recognition rate. The pitches interpret the variance of tones. When they are used as the post processing the error rate is further decreased. |
