A design of the transcoder to convert the VoiceXML documents into the XHTML+Voice documents

Abstract:- Whereas HTML is commonly used for creating graphical web applications, VoiceXML is used for voice-enabled web applications. But those applications that contain a big data or interaction a single-modality are not suited for small and mobile devices. The multimodal markup language like the XHTML plus Voice(X+V) is used for multimodal applications that are composed of VoiceXML-based voice applications and XHTML-based visual applications. It can overcome the limitations of current voice browser and mobile devices by the efficiency of visual display and ease of speech input. And work to maintain different application documents that are formatted to specific devices on the same web service is not economic. Therefore effort to reuse exiting application documents is necessary. In this paper, we propose a new transcoder with an efficient algorithm to convert exiting VoiceXML-based applications into corresponding multimodal applications. The transcoder consists of the voiceXML parser module for fetching VoiceXML documents, the VoiceXML-to-X+V converter module for transforming a VoiceXML tree into a X+V tree on various rules, and the X+V generator module for editing X+V documents about the X+V tree. As a result, all the people who uses telephone and the X+V Browser can access VoiceXML-based services. A service provider can reduce cost and time that are in production and maintenance
