【摘要】 自然语言与GIS结合实现语音GIS有利于提高地理信息服务的智能化,而语音识别及空间信息抽取是实现语音GIS的关键技术。该文探索性研究了利用微软Speech SDK及文法规则匹配实现中文语音GIS的方法,设计和实现了一套语音交互式GIS原型系统。首先,设计了语音交互式GIS实现的流程;其次,研究了Speech SDK接口应用方法、语音触发机制、特征词提取与标注以及文法规则匹配方法;最后,基于ArcGIS Engine 10.2和Speech SDK 5.1实现了原型系统,其主要功能包括基于语音的地图浏览、根据对象名称查询、道路交叉口查询、缓冲区查询、最短路径查询等。实际应用证明,该方法相比现有的ArcGIS软件完成相同查询具有操作步骤少、普适性强、智能化等特点。更多还原

【Abstract】 The combination of natural language and GIS(Geographical Information System)is beneficial to improve the intelligence of the geographic information service.While the speech recognition and spatial information extraction are the key techniques to realize speech GIS.In this paper,the method of developing a Chinese speech interactive GIS based on Microsoft Speech SDK and grammar rule matching was presented,and a prototype speech GIS system was designed and implemented.First,the workflow of implementing speech GIS was studied and designed.Second,great emphasis was laid on the application method of Speech SDK 5.1interface,the speech-triggering mechanism,characteristic words extraction and labeling,and grammar rule matching method.Finally,a speech interactive GIS system was implemented using ArcGIS Engine 10.2and Microsoft Speech SDK 5.1.This system includes several functions,such as the speech-based map browsing,querying object by name,road intersection query,buffer query and shortest path query etc.Experimental results showed that the proposed approach in this paper was available,and compared to the existing ArcGIS software,it had the advantages of less operation steps,strong universality and intelligence in implementing the same query.更多还原
