public class CommandActivity : SpeechSequenceActivity, IEventActivity

Remarks

CommandActivity is matched when the user speaks a phrase that is recognized by the grammar associated with the CommandActivity. In contrast, a SpeechEventActivity represents a system-initiated event in the dialog flow.

CommandActivity represents an event and the associated handler for the event. The CommandActivity provides the event-subscription data. The children of the CommandActivity represent the handler logic for the event.

Two classes that derive from CommandActivity ??? HelpCommandActivity and RepeatCommandActivity ??? can be used to respond to commands for help and to repeat the most recent prompt. A CommandActivity can be used to enable an application to respond to commands other than for help or to repeat a prompt.
