基于语音的奥运信息智能查询系统

提出了一个基于语音交互的奥运信息查询系统。该系统综合应用语音识别、智能人机交互等先进技术,实现了通过语音对历届奥运会的相关信息的查询。在语音识别和问句理解方面,将统计方法与规则方法相结合,利用领域相关知识和受限语言文法,显著地提高了语音识别和问句理解的正确率。实验结果表明,提出和采用的各种技术方法是有效的。

A Speech-based intelligent inquiry system for Olympic information

Along with Beijing 2008 Olympic Games approaching,people pay more attention to Olympic Games.Based on the great demand of Olympic Games information,we proposed a speech-based intelligent inquiry system for the information of Olympic Games.The system synthesizes many kinds of technologies including speech recognition,speech synthesis,natural language understanding,intelligent human-computer interaction techniques,etc.These technologies can help user retrieve information on athlete,Olympic events,medals,scores and so on from Olympic database through speech query.In speech recognition and question understanding,we present a novel method which combines both rule-based and statistics-based natural language understanding together.This method can improve the accuracy of speech recognition and question understanding by using domain-specific knowledge and limited grammar.The experiment result shows that the method we proposed is practical and the system we developed have a good performance in the inquiry process of Olympic Games Knowledge database.
