If you are new to VoiceXML, this overview article will serve as an excellent starting point. For those of you who have already been authoring VoiceXML applications with one of the software developer kits, platforms, and/or on-line developer "web studios" available from various vendors, this article goes beyond the syntactical elements of the language and describes the typical reference architecture in which the VoiceXML interpreter resides.

The VoiceXML Forum last week launched a pilot certification program that marks the start of its effort to promote interoperability of voice applications across platforms, tools and applications. According to Ken Rehor, chair of the Forum's VoiceXML conformance committee, the VoiceXML Platform Certification Program will consist of a series of tests designed to determine whether a VoiceXML platform is fully compliant with the latest release of the specification.

Different projects have different VoiceXML, grammar, audio, and script files associated with them, which may be edited or uploaded. Projects may be local, that is with all files hosted statically on voxBuilder, or remote, by pointing at an external web server under control of the developer. A combination of the two project types is possible as well e.g. host dynamic VoiceXML remotely to the platform but store static audio locally.

This article explains the recommended procedure for performing post-hangup processing on the Tellme Voice Application Network.

This article establishes VoiceXML as an analogue to the familiar realm of HTML. It then moves forward to address the various business opportunities and types of applications that have come into existence with the advent of VoiceXML.

VoiceXML spread like wildfire in 2001. VoiceXML extends the reach and effectiveness of the Web by allowing interactivity and information delivery using voice. VoiceXML can be used to deliver customer service efficiently and inexpensively, just as companies now use HTML to deliver information quickly and cheaply.

Welcome to First Words, VoiceXML Review's column that teaches you about VoiceXML and how you can use it. The Structure of VoiceXML Documents.

This article summarizes the key features of the specification and the application of the specification to VoiceXML application development.

In this monthly column, an industry expert will answer common questions about VoiceXML and related technologies. Readers are encouraged to submit questions about VoiceXML, including development, voice-user interface design, and speech technology in general, or how VoiceXML is being used commercially in the marketplace. If you have a question about VoiceXML, e-mail it to speak.and.listen@voicexmlreview.org and be sure to read future issues of VoiceXML Review for the answer.

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.

"SALT, [in contrast to VXML], is designed for use with multimodal applications, in which you provide input via voice commands and the resulting output is graphical—or vice versa. Such back-end apps are accessed not through standard telephones but through networked mobile devices, including PDAs and Internet-enabled cell phones."

Highlighting the continuing evolution of the telephony market will be a new standard to ease the development of voice response-based interactions on the Web. Advances in communications servers and speech-telephony software will also be demonstrated.

In this article, we will give background as to why HP Bluestone chose this strategy, and provide the reader with all the information necessary to download and explore the functionality of these technologies.

The VoiceXML architectural model specifies a partitioning of application hosting, and application rendering (figure 1). Specifically, the application is served from a Web Server and is typically created dynamically within the framework of an Application Server or equivalent. The VoiceXML Interpreter renders the resultant VoiceXML document, transmitted across a network by HTTP, into a series of instructions interpreted by the Implementation Platform. Implied in this model is a geographical distribution of the application hosting environment and the VoiceXML platform and thus the incursion of network latencies.

This article deals with the development environment that Loquendo has developed and packaged to support companies developing VoiceXML applications for Loquendo's multi-lingual VoiceXML based voice platforms and technologies.

“Web extension or IVR replacement?” While certainly not as profound as the metaphysical “to be or not to be” query posed by Shakespeare’s Danish prince, the question holds great weight for members of the voice commerce and multimodal device community going to market with the latest ASR, TTS and Natural Language solutions.

In this monthly column, an industry expert will answer common questions about VoiceXML and related technologies.

With the launch of the VoiceXML Forum in March of 1999, and the release of the VoiceXML 1.0 specification in March 2000, there has been a surge of activity in the speech and telephony industry around the VoiceXML concept, products and services.

Understanding the network will give you a better feeling for constraints on your voice applications and help you develop better-behaved VoiceXML. This article describes the interaction of high-level network architecture and VoiceXML.
