Type

Application item

Available from

Module Nodes only

Purpose

When using a modular approach to application design, it is often necessary to pass variable or constant values from one module to another. The Module Input item makes it possible for a speech project to pass values into another speech project used as a module. For more information about creating and using application modules, see Module Nodes.

Behavior

When you place a module node in the call flow, Dialog Designer automatically populates it with one Module Input item for each input that the module can accept. If the module was created with Dialog Designer, this means that there is one Module Input item for each Input Parameter item in the speech project being used as the module. See Input Parameter.

If the module was not created with Dialog Designer, you can specify inputs to 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 Input items, much like it does with Dialog Designer-created modules.

To use these items in the speech project, you must assign a value to the Module Input item in the module node. This value can be either a variable value or a constant, but if you do not assign a value in the module node properties, no value is passed to the module node at run time.

Properties

• Name - (Display only) This name is the name of the item in the module that can accept input. If the module was created with Dialog Designer, this is the name assigned to the Input Parameter item. 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 is the default value entered into this field when the module project was created.

• Variable - Select the variable whose value you want to pass in to the module. If the variable you select is a complex variable, you must also select a Variable Field.

• If you enter a Constant value, you cannot also use this field.

• Variable Field - If the variable you selected in the Variable field is a complex variable, you must select from this drop-down list the field whose value you want to pass in to the module. If the variable you selected in the Variable field is a simple variable, this field is blank.

• Constant - Enter in this field the exact string or value you want to pass in to the module.

• If you use this field, you cannot also use the Variable field.
