Purpose

When using a modular approach to application design, it is often necessary to pass variable values from one module to another. The Module Output item makes it possible for a speech project used as a module node to pass such data back to the parent speech project.

Behavior

When you place a module node in the call flow, Dialog Designer automatically populates it with one Module Output item for each output value that the module passes to the parent application. If the module was created with Dialog Designer, this means that there is one Module Output item for each Output Parameter item in the speech project being used as the module. See Output Parameter.

If the module was not created with Dialog Designer, you can specify outputs from the module when you import the module into Dialog Designer. Then, when you use the module in a Dialog Designer speech application, Dialog Designer automatically populates it with the required Module Output items, much like it does with Dialog Designer-created modules.

Note:

Currently, Dialog Designer supports only Nuance OSDMs for import into Dialog Designer applications. Dialog Designer supports the following OSDM versions: Address OSDM 2.0.3, Core OSDM 2.0.4, and Name OSDM 2.0.1.

At the same time, Dialog Designer automatically creates:

A complex variable with the same name as the module node.

A field for that variable with the same name as the name of the Module Output item in the module node.

You can use the returns to this variable and variable field as you would use any other variable and variable field.

Properties

Name - (Display only) This field is the name assigned to the Module Output item when the module was named. If the module was created with Dialog Designer, this name is the same as the name of the Output Parameter item in the speech project being used as the module. You cannot change it here.

Description - (Display only) This field is the description entered into this field when the module project was created.

Default Value - (Display only) This field displays the value of the variable assigned to the Variable property of the Output Parameter item in the module that is passing the variable information to the parent application.
