The Set Step

Continue the No output branch of the Implicit Confirmation step by dragging a Set step from the Prompt palette to the Design pane, and dropping it over the second Create Conditional Prompt step icon under the Implicit Confirmation step icon, as shown in figure Name To User—No Output Branch of Implicit Confirmation Step.

Then configure the Set step to assign the system grammar SG[AA/AAWantToCall] to the grammar variable. This choice instructs the script how to interpret spoken input from the caller.
