This paper suggests realization method for real-time speech recognition using VoiceXML in telephony environment based on SIP for Railroad Reservation Service. In this method, voice signal incoming through PSTN or Internet is treated as dialog using VoiceXML and the transferred voice signal is processed by Speech Recognition System, and the output is returned to dialog of VoiceXML which is transferred to users. VASR system is constituted of dialog server which processes dialog, APP server for processing voice signal, and Speech Recognition System to process speech recognition. This realizes transfer method to Speech Recognition System in which voice signal is recorded using Record Tag function of VoiceXML to process voice signal in telephony environment and it is played in real time.

A new brilliant service using human-voice and DTMF (Dual Tone Multi Frequency) technique is expected nowadays in order to obtain valuable information on the internet more easily. VoiceXML (Voice eXtensible Markup Language) is the right choice that makes the new service possible. In this paper, the design and implementation of IVR (Interactive Voice Response) server using VoiceXML is described, where it connects with internet and IVR server efficiently. IVR server using VoiceXML is composed of two groups: VoiceXML document handling and VoiceXML execution. Scenario part of IVR server corresponds to VoiceXML document, the execution is performed by VoiceXML execution.

VoiceXML is a standard dialog mark-up language for the neat generation voice applications. The current VoiceXML 1.0 specification is silent on who place outbound calls for push-based voice applications. The push-barred voice applications become very important in modern information systems such as CRM. In this paper, we design and implement an extended VoiceXML platform that supports both inbound and outbound voice information services. We also extend the VoiceXML DTD so as to be able to inbound/outbound fax based on Call Control Requirements of W3C.

In this paper we suggest a method for translating (or integrating) XML documents into Voice XML documents in order to provide voice communication service. In the forthcoming web environment, XML will certainly overwhelms HTML. At this situation, the method of accessing data through the more various types of terminal machines is required.'rho best way is to use Voice XML by which the data accessing method is able to change from Web to the wired or/and wireless terminal at low costs. Thus we suggest a method for integrating the XML-based system into the Voice XML-based one.

In this paper, we propose an interpreter, which recognizes the VoiceXML markups, verifies the validation of the document, and interprets the VoiceXML documents using DI parser and the generated AST by the parser. The VoiceXML interpreter consists of DI parser and executor, and the DI parser uses recursive descent parsing technology, and the executor uses FIA (Form Interpretation Algorithm) proposed by VXML forum. This system uses the Java language in order to develop the runtime environment for VoiceXML efficiently, thus this system has portability.

대화형 음성 응답 시스템은 비용이 많이 들고 폐쇄된 환경에서만 개발이 가능했었지만 VoiceXML이라는 표준화된 문서의 개발로 인하여 새로운 국면을 맞이하게 되었다. 본 논문에서는 관계형 데이터베이스를 기반으로 한 다이얼로그 단위로 분리 저장하는 VoiceXML 문서 저장 시스템을 설계하고 구현하였다. 음성을 서비스할 수 있는 VoiceXML 문서를 관계 데이터베이스를 이용하여 VoiceXML 문서 저장 모델을 설계하고 VoiceXML 문서의 구조적 정보를 효과적으로 표현하고 저장하는 방법을 제안한다.

In this paper we studied English listening and speaking test part of foreign language using web and VoiceXML-based education testing system, which is irrespective of time and space. The testing system interface based on VoiceXML consists of user registration module, testing module, and testing result module. User registration module registers user's name and ID, password in user database, and when a tester calls for testing, the User listens to the telephone sound supported by vxml scenario. After that, if a tester logs in, the tester is verified, In the VoiceXML-based education testing system, the manager can reduce time and effort for gaining testing result. The tester listens to the voice by scenario supported by VoiceXML markup language using wire/wireless telephone at any time or anywhere and can improve the effect of foreign language studying by valuating in voice directly. verified.

As there are needs to search the Web information via wire or wireless telephones, VoiceXML forum was established to develop and promote the Voice eXtensible Markup Language (VoiceXML). VoiceXML simplifies the creation of personalized interactive voice response services on the Web, and allows voice and phone access to information on Web sites, call center databases. Also, it can utilize the Web-based technologies, such as CGI(Common Gateway Interface) scripts. In this paper, we have developed the voice portal service platform based on VoiceXML called TeleGateway. It enables integration of voice services with data services using the Automatic Speech Recognition (ASR) and Text-To-Speech (TTS) engines. Also, we have showed the various services on voice portal services.

VoiceXML is new markup language which is designed for web resource navigation via voice based on XML. An application using VoiceXML is classified into mutual-controlled and machine-controlled form dialog structure. Such dialog structures can't construct service which provide free navigation of web resource by user because a scenario is decided by application developer. In this paper, we propose VoiceXML application structure using user-controlled form dialog system which decide service scenario according to user's intention. The proposed application automatically detects recognition candidates from requested information by user, and then system uses recognition candidate as voice-anchor. Also, system connects each voice-anchor with new voice-node. An example of proposed system, we implement news service with IT term dictionary, and we confirm detection and registration of voice-anchor and make an estimate of hit rate about measurement of an successive offer from information according to user's intention and response speed. As the experiment result, we confirmed possibility which is more freely navigation of web resource than existing VoiceXML form dialog systems.
