The application—which combined speech, VoiceXML and the web—provided children with an opportunity to have a personalized ‘chat’ with S.

You can build powerful voice applications using VoiceXML and JavaScript. These languages are executed by the VoiceXML interpreter to handle call flow logic and user interaction. To tie your phone application into back-end systems such as databases and middle-tier business logic, your voice application needs some way to interact with those systems.

This document provides a guide to implementing the rules of ECMAScript (JavaScript) as applied to the VXML specification using the ScriptEase ISDK.

The voxBuilder ODE supports development in both VoiceXML 1.0 and VoiceXML 2.0. The first version of VoiceXML was the result of a collaboration of work from AT&T, Lucent, Motorola and IBM and was released under the auspices of the VoiceXML Forum. The evolution of the VoiceXML specification is now the responsibility of the W3C.

VoiceXML looks a lot like HTML. In fact, its designers hope that VoiceXML will mediate the creation of a "voice web" just as HTML mediated the creation of the visual Web. While this may very well happen, the more immediate beneficiaries of VoiceXML are not Internet users, but telephone companies, call center operators, and telephone-based CRM operations.

The VoiceXML revolution is just beginning. Only within the past few months have VoiceXML interpreters become robust, feature-rich and capable of supporting a carrier-grade commercial application. Work still remains to further improve scalability, efficiency and density, and even to agree on a common interpretation for every tag and attribute in the specification. This article assumes that carrier-grade VoiceXML interpreters will continue to mature and evolve, and focuses instead on the challenges of developing a commercial-grade VoiceXML application to run on the interpreter.

A voice-based application is as frustrating as a traffic jam if it doesn't meet the user's expectations. This article takes you step by step through the process of usability testing your VoiceXML application.

This tutorial teaches you how to develop Voice Extensible Markup Language (VoiceXML) based applications. The course is intended for developers and technical managers who want to get an overview and understanding of VoiceXML application development.

The OpenVXI is a portable open source based toolkit that interprets the VoiceXML dialog markup language. It is designed to serve as a framework for system integrators and platform vendors who want to incorporate VoiceXML into their platform.

Imagine, for a moment, a technology being accessed by two billion people -- roughly a third of the world's population. According to a recent study from Datacomm Research, that's just the number of people who will use Internet voice portals, voice-enabled Web sites, and Web-based voice response systems by the year 2005.

The VoiceXML Forum and the World Wide Web Consortium (W3C) Tuesday reached an agreement under which the W3C will take the lead in technical development while the VoiceXML Forum focuses on interoperability.

So you want to develop and deploy a VoiceXML application, but you're not sure whether to build your own VoiceXML gateway, buy a turnkey solution, or host your application? This article will lay out the pros and cons when considering a VoiceASP and discuss the features, costs, and tools provided by each of the top vendors.

An area where we have an opportunity to make VoiceXML easier to use and more portable is in development and runtime tools. VoiceXML provides two significant advantages in authoring speech-enabled applications, when compared to previous methods. It allows a developer to build speech services with less effort and it allows applications written for one speech platform to run on another speech platform.

In this article we will discuss how caching can be used to enhance the performance of VoiceXML applications. Caching is a strategy for storing temporary 'objects' (e.g. VoiceXML resources) local to the VoiceXML Interpreter that can be employed by the application developer for optimising these latencies.

IBM has announced the WebSphere Voice Application Access middleware product designed to simplify "building and managing voice portals and to more easily extend web-based portals to voice. Leveraging the scalability, personalization, and authentication features of IBM's WebSphere Portal, it enables mobile workers to more easily access information from multiple voice applications -- using a single telephone number.

So what's new with VoiceXML 2.0? Plenty. What was a single language, VoiceXML 1.0, has been extended into several related markup languages, each providing a useful facility for developing web-based speech applications. These facilities are organized into the W3C Speech Interface Framework.

VoiceXML is the industry's open, standards-based development language for voice-driven solutions. It is endorsed by the W3C, the same organization that defines other key standards such as HTML. A growing number of carriers and corporations around the world use VoiceXML for customer care and enhanced service applications.

Many questions must be answered for the VoiceXML class of applications. This article summarizes some of the critical issues that must be addressed even before the actual development begins.

The VoiceXML Reference is available for download here.

In this article, we examine some of the key changes in the first public working draft of VoiceXML 2.0 as compared to the VoiceXML 1.0 specification.
