Overview

The WebSphere Voice Toolkit is an enhanced collection of technologies for creating sophisticated voice applications. It is powered by Eclipse technology and makes it easy to develop VoiceXML applications without having to know the internals of voice technology:

  • It provides the tools to build, debug, and deploy voice applications for use with IBM WebSphere Voice Response and MRCP V1.0 speech servers.
  • Its features include a full-featured voice development environment including call flow building, VoiceXML development and debugging, Grammar development and debugging, and Call Control Extensible Markup Language (CCXML) development.
  • It includes Graphical Grammar Builder for visual composition of a grammar file for speech recognition, and graphical Communication Flow Builder for automatic generation of VoiceXML.

Features and benefits

Product features of WebSphere Voice Toolkit include:

  • Communication Flow Builder
  • Graphical Grammar Builder
  • VoiceXML 2.1 support
  • VoiceXML editor
  • Call Control eXtensible Markup Language (CCXML) editor
  • Built-in audio recorder
  • Audio analysis tool
  • VoiceXML Conversion wizard from 1.0 to 2.0, 1.0 to 2.1 or 2.0 to 2.1
  • Grammar Conversion wizard from JSGF to SRGS, BNF to SRGS, or SRGS to SRGS (XML➝ABNF or ABNF➝XML)

It has a number of key features:

  • It provides the ability to create applications for the VoiceXML 2.1 application programming model and voice technologies.
  • The Communication Flow Builder-a graphical tool for visual composition of a voice application, based on GEF (Graphical Editing Framework) technology. The concept is similar to that of a flowchart diagram, with nodes, links, and decision points. The palette of nodes can be used to describe the flow of most VoiceXML applications.

    The tool provides an easy to use way to design and prototype a voice application by someone who is not familiar with VoiceXML programming, for proof-of-concept demonstrations and generation of executable VoiceXML code. One will be able to construct the entire application visually, test the flow, create grammars and prompts, and produce reports and metrics based on analysis of the call flow.

  • Call Control eXtensible Markup Language (CCXML) editor: The CCXML Editor extends the base XML editor to provide a development tool for CCXML (Call Control) markup, for purposes of creation and modification of CCXML documents. This editor provides a set of functions similar to the VoiceXML editor (Preference management, formatting, validation, etc.) except it is based on the proposed CCXML standards. For more information about CCXML, see http://www.w3.org/TR/ccxml/.
  • Grammar Weighting Tool allows users to weight their grammars files based on user-collected data
  • Variable DTD - The ability to specify an XML DTD file has been added to all of the XML based editors (VoiceXML, CCXML, and SRGS XML). This allows the user to validate and provide Content Assist based on the actual DTD that will be used by their deployed application.
  • Support for MRCP (Media Resource Control Protocol) V1.0 capabilities.

Installation

Important: If you have already installed the WebSphere Voice Toolkit, you must uninstall it before reinstalling. To do this, follow the steps in Uninstalling.

To install the WebSphere Voice Toolkit V6.2:

  1. If you have not already done so, download the Eclipse IDE for Java EE Developers V3.7.1 from http://www.eclipse.org/downloads, and install it. (You can use other editions of Eclipse V3.7.1, but if you do so, you all must import the WST plugins required by the WebSphere Voice Toolkit.)
  2. Download the .zip file. See the Downloads section.
  3. Start an instance of Eclipse.
  4. Click Help -> Install New Software to display the Install window.
    Installation dialog
