Loosely-coupled approach towards multi-modal browsing

Contemplating the concept of universal-access multi-modal browsing comes as one of the emerging killer technologies that promises broader and more flexible access to information, faster task completion, and advanced user experience. Inheriting the best from GUI and speech, based on the circumstances, hardware capabilities, and environment, multi-modalitys great advantage is to provide application developers with a scalable blend of input and output channels that may accommodate any user, device, and platform. This article describes a flexible multi-modal browser architecture, named Ferda the Ant, which reuses uni-modal browser technologies available for VoiceXML, WML, and HTML browsing. A central component, the Virtual Proxy, acts as a synchronization coordinator. This browser architecture can be implemented in either a single client configuration, or by distributing the browser components across the network. We have defined and implemented a synchronization protocol to communicate the changes occurring in the context of a component browser to the other browsers participating in the multi-modal browser framework. Browser wrappers implement the required synchronization protocol functionality at each of the component browsers. The component browsers comply with existing content authoring standards, and we have designed a set of markup-level authoring conventions that facilitate maintaining the browser synchronization .     

VoiceXML dialog system of the multimodal IP-Telephony—The application for voice ordering service

The development of IP-Telephony in recent years has been substantial. The improvement in voice quality, the integration between voice and data, especially the interaction with multimedia has made the 3G communication more promising. The value added services of Telephony techniques alleviate the dependence on the phone and provide a universal platform for the multimodal telephony applications. For example, the web-based application with VoiceXML has been developed to simplify the human–machine interaction because it takes the advantage of the speech-enabled services and makes the telephone-web access a reality. However, it is not cost-efficient to build voice only stand-alone web application and is more reasonable that voice interfaces should be retrofitted to be compatible or collaborate with the existing HTML or XML-based web applications. Therefore, this paper considers that the functionality of the web service should enable multiple access modalities so that users can perceive and interact with the site in either visual or speech response simultaneously. Under this principle, our research develops a prototype system of multimodal VoIP with the integrated web-based Mandarin dialog system which adopts automatic speech recognition (ASR), text-to-speech (TTS), VoiceXML browser, and VoIP technologies to create user friendly graphic user interface (GUI) and voice user interface (VUI). The users can use traditional telephone, cellular phone, or even VoIP connection via personal computer to interact with the VoiceXML server. In the mean time, the users browse the web and access the same content with common HTML or XML-based browser. The proposed system shows excellent performance and can be easily incorporated into voice ordering service for a wider accessibility.     

The implementation of a secure and pervasive multimodal Web system architecture

While most users currently access Web applications from Web browser interfaces, pervasive computing is emerging and offering new ways of accessing Internet applications from any device at any location, by utilizing various modes of interfaces to interact with their end users. The PC and its back-end servers remain important in a pervasive system, and the technology could involve new ways of interfacing with a PC and/or various types of gateways to back-end servers. In this research, cellular phone was used as the pervasive device for accessing an Internet application prototype, a multimodal Web system (MWS), through voice user interface technology.This paper describes how MWS was developed to provide a secure interactive voice channel using an Apache Web server, a voice server, and Java technology. Securing multimodal applications proves more challenging than securing traditional Internet applications. Various standards have been developed within a context of Java 2 Micro Edition (J2ME) platform to secure multimodal and wireless applications. In addition to covering these standards and their applicability to the MWS system implementation, this paper also shows that multimodal user-interface page can be generated by using XSLT stylesheet which transforms XML documents into various formats including XHTML, WML, and VoiceXML.
