Getting Started

To launch the WebSphere Voice Toolkit, start the Eclipse workbench into which the toolkit has been installed.

For information on using the toolkit, refer to the online Help. From the Help menu, click Help Contents. When the Help window appears, select Developing Voice applications from the list.

For additional information about the samples included with the toolkit, see the sample readme files that are located in each of the sample directories in <Eclipse_install_dir>\eclipse\plugins\com.ibm.voicetools.samples_6.1.0

What's new

The following features and functions are new or updated in this release:

Eclipse and Web Tools Platform Pre-requisite
This version of the WebSphere Voice Toolkit can be used with any installation of Eclipse 3.2 and the Web Tools Platform 1.5.2, including IBM Rational SDP 7.0.

Transcription Tool
Listen to audio segments (local files or URIs) and provide transcriptions for them to be used for recognition accuracy analysis. A transcription file can be exported from and used by either the Voice Trace Analyzer or the Batch Grammar Test Tool.

Grammar Weighting
Ability to add weights to the rules of a grammar file to improve the recognition accuracy of a grammar.

Lexicon Migration
The latest version of the Latin American Spanish (es-MX) acoustic model has a different ASR phonology from the previous versions included with WebSphere® Voice Server V.5.1.X. If you previously created lexicon files that you want to use with the latest version of WebSphere Voice Server, then the toolkit provides a way for you to migrate these lexicon files using the Lexicon Migration wizard. The converted files contain the new phonemes in the phoneme tags.

Batch Grammar Test Tool
Allows you to automate the testing of a large number of grammars and audio files (local files or URIs), analyze the recognition accuracy of the test, and compare the results with previous tests.

Local Voice Server Environment Removed
The WebSphere Voice Toolkit no longer installs speech technology, an MRCP server, or a VoiceXML browser in the development environment. All speech-related functions, such as grammar testing and pronunciation generation, will now require an MRCP connection to a WebSphere Voice Server installation. The features to start and stop the Voice Server ("Start Voice Server" and "Stop Voice Server" menu items) are removed from the Run menu.

Lexicon Editor (updated)
Support the .lexml and .pls file extensions and provide more useful information to the Outline view.

Voice Trace Analyzer (updated)
Displays information and statistics on the grammar recognition events that have been logged on a WebSphere Voice Server system, with additional analysis of recognition accuracy for tuning of the grammars and server settings. Allows you to export the list of audio files to be transcribed, perform that transcription offline, and import the transcriptions into this tool for further statistical analysis of the accuracy. Gathers the Synthesis events from the collected logs and displays them in a table in a new Synthesis tab, as well as interleaving them in with the Recognition events in the Call Flow tab.

Editors

  1. In the Navigator view, right click on the project, and on the pop-up menu, click Properties.
  2. On the Properties dialog, select Validation. Also select the Override validation preferences check box, and clear the SRGS-XML Form Validator check box.
  3. Click Apply, and then click OK.

Note:
This turns off the SRGS-XML editor validation, but the compiler's XML validation still occurs.
