Envox VoiceXML studio shares many of the same elements of Envox Studio. Developers will be working with a different set of audio properties to define and manage prompts and responses based on the VoiceXML standard, however. This means that the scope of packaged elements is more limited than in Envox Studio, with Envox VoiceXML Studio including more basic elements that require the developer to create specific types of database interactions or new menus.

We like the way Envox VoiceXML Studio puts element properties at hand in a separate window. Each element has a number of predefined properties. For example, the credit-card-transaction element has fields for collecting and confirming data points such as credit card numbers, ZIP codes and security codes.

Elements include common modifiable settings for assigning a confidence level for voice or touch-tone transactions. With these settings we could also define the vocabulary we expected a caller to use for a given menu item. Through the properties windows, we defined audio prompts that accessed the text-to-speech engine, as well as transaction logging.

Developers can use Envox VoiceXML Studio independent of Envox Studio to create VoiceXML 2.0-compatible files that can be used with any VoiceXML 2.0-compliant speech application platform. In addition to saving scripts in VoiceXML, Envox VoiceXML Studio generates projects as JavaScript code that can run on either Envoxs own application server or an application server such as IBMs WebSphere.
