Creating Speech Applications with Dialog Designer > Building Applications
	Building Applications

The basic process of building speech application projects in Dialog Designer involves:

• Placing nodes in the workspace area

• Connecting them to create a call flow

This call flow represents the possible paths a caller can follow while interacting with your interactive voice response (IVR) system. See Working with the Call Flow Editor.

About Nodes

Each node is represented by an icon and label on the options palette. When placed in the workspace, the node represents a functional piece of code that performs some action, such as:

• An announcement that is played to callers when they first call in to the system.

• A menu that offers callers options from which they can select, responding either by speaking or by pressing touchtone keys on their telephones.

• A data transaction that sends data collected from a caller to a customer database. The data transaction then retrieves information from that database to present to the caller.

For more information on the types of nodes available in Dialog Designer, see Getting Familiar with Nodes to Build Applications.

Placing Nodes and Other Items

Dialog Designer requires a click-and-drop technique to place nodes and other items in the Editor view workspace. Usually, to place a node or item in the workspace:

1. Click the desired node or item on the options palette.

2. Click again in the workspace at the location you want to place the node or item.

Specific details for placing nodes or items in the workspace are provided, if applicable, where those nodes or items are discussed.

Connecting Nodes

After two or more nodes are placed in the workspace, the can be connected according to the call flow design. To connect nodes, see Working with the Call Flow Editor.

Defining Nodes and Other Items

After the system displays the node or item in the workspace, the node can be further defined or modified. Do this by clicking the node icon and then filling in or selecting properties in the Properties view. Some properties can be directly edited in the node editor for that node.

Almost any node or item can be edited in the Editor view workspace. In fact, to make sure the work the way they are intended to work, they must be edited. For more information about editing nodes and other flow items, see Call Flow Editor Palette Action Options and Nodes and Palette Options.

Many nodes also require being populated with one or more application resources, such as phrases, prompts, and grammars. See Using Application Resources.
