Tellme Networks: VoiceXML Leadership and Innovation

VoiceXML is a thriving, open standard that makes it possible for businesses to unify their Web and IVR infrastructure, consolidate investments, and deliver a seamless experience to their customers.

Successful open standards mature and grow through a healthy, ongoing cycle of innovation, adoption, and standardization. Leading vendors pioneer new features to address customer requirements. Over time, some of those features achieve significant market adoption because customers find them useful. Ultimately, these features become accepted and officially codified within the open standard, and all vendors implement them in a compatible way. As one of the editors coauthoring the VoiceXML standard in the W3C, Tellme Networks is firmly committed to this process and continually seeks to help drive this cycle of innovation, adoption, and standardization.

Tellme regularly develops new features in response to customer requirements. At the same time, Tellme maintains a fully compliant implementation of the VoiceXML standard. Tellme customers have complete freedom to choose what features they use when building applications on the Tellme Voice Application Network. They can optimize for cross-platform compatibility by choosing to adhere strictly to existing standardized functionality, or they can choose to take advantage of newer features that are available, but earlier in the standardization process.

Examples of VoiceXML innovations pioneered by Tellme include:

subdialog (included in VoiceXML 2.0). This element allows for modular programming in VoiceXML.
log (included in VoiceXML 2.0). This element allows developers to write custom messages to the call log for further analysis.
data included in VoiceXML 2.1). This element gives rich client-side access to data using the same programming model provided by Microsoft Internet Explorer. VoiceXML applications use the dataelement to fetch XML data across the Internet and then manipulate that data using JavaScript and the standard XML DOM. This gives developers much greater flexibility when developing dynamic voice applications that integrate with back-end data.
foreach (included in VoiceXML 2.1). This element adds the ability to iterate through an JavaScript array, allowing tighter and richer integration between JavaScript and native VoiceXML elements.

As a leading VoiceXML platform provider, Tellme systematically proposes all new features it develops to the W3C for consideration in the standards process, and all such features are clearly marked in the Tellme Studio Platform SDK documentation.
