Abstract

维吾尔语广播新闻敏感词检索系统是以HMM为基础.在MATLAB平台上设计实现的.该系统的特点包括:1.由于维吾尔语敏感词数量不多,该系统语音语料库很小.2.由于广播新闻中的发音较为标准规范,在识别中避免了说话人发音上的不规范,这有利于语音识别系统性能的提高.3.由于选择词素为识别基元,易于识别基元端点检测.

Other Abstract

In this paper,we introduce the research and implementation of a HMM based Sensitive-word Spotting System for Uyghur Broadcast News.Our system has three advantages to be exploited.First,the speech corpus is very small because it has finite number sensitive-word.Second,the broadcast news word pronunciation is clear and the property of word speed is regular,which is beneficial to the recognition.Third,in our system,we used whole-word models as the basic speech unit,since the whole word has the property of well-defined acoustic representation,which facilitate the segmentation of the beginning and the end of the word.
