A Voice-Enabled Pervasive Web System with Self-Optimization Capability for Supporting Enterprise Applications

Abstract

Other than providing Web services through popular Web browser interfaces, pervasive computing may offer new ways of accessing Internet applications by utilizing various modes of interfaces to interact with their end-users, and its technology could involve new ways of interfacing with various types of gateways to back-end servers from any device, anytime, and anywhere. In this chapter, mobile phone was used as the pervasive device for accessing an Internet application prototype, a voice-enabled Web system (VWS), through voice user interface technology. Today’s Web sites are intricate but not intelligent, so finding an efficient method to assist user searching is particularly important. One of these efficient methods is to construct an adaptive Web site. This chapter shows that multimodal userinterface pages can be generated by using XSLT stylesheet which transforms XML documents into various formats including XHTML, WML, and VoiceXML. It also describes how VWS was designed to provide an adaptive voice interface using an Apache Web server, a voice server, a Java servlet engine, and a genetic algorithm based voice Web restructuring mechanism.
