Nowadays the corporations related to Information & Communication field are researching more and more on VoiceXML development. VoiceXML can provide users with more efficient interface, VUI(VoiceXML User Interface) in web environment than the existing one. But more research and development for designing the Dialog have to be done for VUI to be used in efficient way. That was a main topic in "2002 VoiceXML Conference & Expo". According to the importance this paper presents VoiceXML Dialog designed for the purpose of its efficient use and the experimental result.

The present Web surroundings is composed of HTML(Hypertext Mark-up Language) and thereby users obtains web informations mainly in GUI(Graphical User Interface) environment by clicking mouse in order to keep up with hyperlinked informations. However it is very inconvenient to work in this environment comparing with easily accessed one in which human's voice is utilized for obtaining informations. Using VoiceXML, resulted from XML, for supplying the information through telephone on the basis of the contemporary matured technology of voice recognition/synthesis to work out the inconvenience problem, this paper presents the research results about VoiceXML Web Browser designed and implemented for realizing its technology.

In this paper, we design and implement a multiple-view VoiceXML editor to improve editing efficiency of the VoiceXML. The VoiceXML multiple-view Editor uses a MVC framework to support multiple views and paradigm. Our multiple-view editor consists of Model. View and Controller using MVC framework. A model, core data structure. is constructed of abstract syntax tree and abstract grammar. A view. user interface. is formalized in unparsing rules and unparser. A controller. to control model and view. is made of command interpreter and tree handler. The VoiceXML multiple-view editor overcomes a drawbacks of existing XML editors by showing document structure and context concurrently. as well as document flows. Our VoiceXML multiple-view editor. which MVC framework has been applied, provides various editing views concurrently to users. Thereby. it supports efficient and convenient editing environments for voice-web documents to users and it guarantees transparency of editors. as various views have a same consistent model.

The present web informations are mainly described in terms of HTML, which users obtain through input devices such as mouse, keyboard, etc. Thus the existing GUI environment have not supported human's most natural information acquisition means, that is, voice. To solve the problem, several vendors are developing voice user interface. However these products are deficient in man -machine interactivity and their accommodation of existing web environment. This paper presents a VUI(Voice User Interface) supporting web browser by utilizing more and more maturing speech recognition technology and VoiceXML, a markup language derived from XML. It provides users with both interfaces, VUI as well as GUI. In addition, XML Island technology is applied to the bowser in a way that VoiceXML fragments are nested in HTML documents to accommodate the existing web environment. Also for better interactivity, dialogue scenarios for menu, bulletin, and search engine are suggested.

In this paper, we implemented practical application service using VoiceXML. Developers can utilize the advantages of using VoiceXML such as reducing development time and sharing contents between applications. Up to now, speech related services were developed using APIs and programming languages such as C/C++ or exclusive developing tools, which methods depend on system architectures. For this reasons, reuse of contents and resources was very difficult. If developers want to change scenarios of the application services or change platforms, they have to edit and recompile their program sources. To solve these problems, nowadays, companies develop their applications using VoiceXML. But, there's poor grip of actual problems can be occurred when they use VoiceXML. To overcome these problems, we implemented stock trading system using VoiceXML. We found out problems which occurred during developing services. We proposed solutions to these problems And, we analyzed strong points and weak points of applications using suggested system.

본 연구에서는 기존의 전통적인 IVR 시스템이 갖는 제약을 해결할 수 있는 XML 포맷을 가지는 VoireXML 문서를 브라우징할 수 있는 Voice 브라우저를 설계ㆍ구현하였다. VoiceXML로 기술된 다이얼로고를 VoiceXML 인터프리터를 통하여 해석하고 추출된 폼을 FIA로 해석하게 하였으며 음성인식 엔진의 컴포넌트를 이용하여 Grammar 컴파일 및 음성 입ㆍ출력이 가능하도록 하였다. 본 연구의 브라우저를 기반으로 하는 시스템은 음성 언어 어플리케이션을 개발할 시에 음성 인식과 같은 복잡한 기술을 이용하지 않아도 되며 현재 웹 개발의 이점을 이용할 수 있다.

음성 기술의 발달과 VoiceXML 1.0의 제정으로 인해 표준화된 방식으로 이동 단말기와 전화를 통해 음성으로 웹 컨텐츠에 접근할 수 있게 되였다. 거의 모든 웹 컨텐츠들은 HTML로 작성되어 있으며, 기존의 HTML로 작성된 수많은 웹 컨텐츠에 음성으로 접근하기 위해서는 HTML 문서들을 VoiceXML 문서로 변환하여야 한다. 이를 수동으로 변환하기 위해서는 많은 시간과 비용이 필요하게 된다. 본 논문에서는 이 문제를 해결하기 위해여 HTML 문서률 VoiceXML 문서로 자동 변환하는 HTMLtoVoiceXML변환기의 설계 방안을 제시하였다.

In this paper, we design and implement practical application service using VoiceXML. And we suggest new solutions of problems can be occurred when implementing a new systems using VoiceXML, based on the fact. Up to now, speech related services were developed using API (Application Program Interface) and programming languages, which methods depend on system architectures. It thus appears that reuse of contents and resource was very difficult. To solve these problems, nowadays, companies develop their applications using VoiceXML. Advantages of using VoiceXML when developing services are as follows. First, we can use web developing technologies and technologies for transmitting web contents. And, we can save labors for low level programming like C language or Assembler language. And we can save labors for managing resources, too. As the result of these advantages, we can reduce developing hours of applications services and we can solve problem of compatibility between systems. But, there's poor grip of actual problems can be occurred when implementing their own services using VoiceXML. To overcome these problems, we implemented interactive stock trading system using VoiceXML and concentrated our effort to find out problems when using VoiceXML. And then, we proposed solutions to these problems and analyzed strong points and weak points of suggested system.

현재의 웹 환경은 HTML로 구성이 되어있고 이로인해 하이퍼링크를 따라가기 위해 마우스 클릭을 통해 작업하는 GUI환경이 주를 이룬다. 하지만 이러한 방법은 인간이 가장 손쉽게 사용하는 음성과 비교해 볼때 상당히 불편한 축에 속한다. 이를 해결하기 위해 현재 무르익은 음성인식 기술과 전화기를 통해 정보를 제공하고자 하는 XML의 파생인 VoiceXML을 이용하여 현재 HTML이 주류를 이루는 웹 환경을 VoiceXML을 이용한 음성인터페이스 환경을 마련하고자 한다.
