摘要: 语音识别的精度不够高始终是限制其广泛应用的瓶颈。针对具体应用中关键词汇和短语有限的特点,提出了音节相似度的概念,通过计算语音识别结果与应用域关键短语集合的音节相似度,找出最匹配结果,可有效提高语音识别应用的成功率。提出音节相似度的概念,给出利用音节相似度设计开发校园网语音浏览系统的过程。

Abstract:

It is a bottleneck of application of speech recognition that the accuracy of speech engine is not high enough.But in some cases we may obtain ideal accuracy using context knowledge.If speech input is one element of a finite set,the accuracy can be improved greatly using syllable similarity.The definition of syllable similarity is described,the procedure of design and development of speech inquire system based syllable similarity is given.
