Deploying speech applications over the web

Abstract

At Digital Equipment Corporation's Cambridge Research Lab (CRL), the Speech Interaction Group has been focus-ing on building speech applications for deployment over the World-Wide Web. Web-based speech applications re-quire the browser to capture and transmit speech to re-mote servers for back-end processing, maintain applica-tion state, and present multi-media responses. This pa-per describes the group's strategy for delivering speech applications built around a mechanism, the digital Voice Plugin, for capturing and transmitting audio from a browser. It describes a conversational application imple-mented within this framework and discusses the problems of delivering these systems on the Web. In addition, we brie y touch upon some other Web-based speech applica-tions that have been developed at CRL. 1.
