The fields in the Voice Application Settings contain values required for successful compilation and deployment as well as defaults that apply throughout the application.
The voice application fields appear in the Task Panel when you double-click on the workspace of a voice application model. If this does not appear, from the task-panel toolbar choose Configure.
If you want to define other default settings for the application than those provided, for example, another language, choose Settings. All User-Defined Entities apply as defaults over the entire application, unless you specifically override them by child Voice Components or Listen Elements.
The application data can be classified as fields that can be configured or application defaults.
