HMM关键词检出系统

关键词检出(keywordspottin)g也称词检出(wordspottin)g,是近年来语音识别中颇受重视的研究领域,可广泛应用于电话的自动接听和对话监听、语音的录入和检索等方面。文中首先介绍了关键词检出的HMM方案及其研究成果,并对其进行了仿真实验,最后指出了关键词检出尚待解决的一些问题及研究方向。

Keyword Spotting(Word Spotting) is one of the most active areas on speech recognition in the latest decades. This technology can be applied to real-time phone operator and monitor, automatic speech dictation and searching, etc. This paper first describes the development of HMM methods of keyword spotti ng, then introduces the experiments simulating the method in lab. Finally this a rtical indicates some problems of keyword spotting and its trends of the researc h.
