Example

The following code example shows the creation of a QuestionAnswerActivity instance, askDrink. After askDrink is created, a number of its properties are set. In the highlighted line of code, TurnStarting is registered to be handled by askDrink_TurnStarting, the event handler for this event.

this.askDrink = new Microsoft.SpeechServer.Dialog.QuestionAnswerActivity();
this.askDrink.CanBargeIn = true;
this.askDrink.CompleteTimeout = System.TimeSpan.Parse("00:00:01.5000000");
this.askDrink.InitialSilenceTimeout = System.TimeSpan.Parse("00:00:01.5000000");
this.askDrink.Name = "AskDrink";
this.askDrink.TurnStarting += new System.EventHandler<Microsoft.SpeechServer.Dialog.TurnStartingEventArgs>(this.askDrink_TurnStarting);
askDrink.Prompts.HelpPrompt.AppendText(GetPromptResource("askDrink_HelpPrompt"));
askDrink.MainPrompt.AppendText(GetPromptResource("askDrink_MainPrompt"));
askDrink.Grammars.Add(new Microsoft.SpeechServer.Recognition.Grammar(new System.Uri("Grammars\\Drinks.grxml", System.UriKind.RelativeOrAbsolute), "Drinks"));
askDrink.DtmfGrammars.Add(new Microsoft.SpeechServer.Recognition.Grammar(new System.Uri("Grammars\\DigitsDTMF.grxml", System.UriKind.RelativeOrAbsolute), "digit"));
this.Activities.Add(this.askDrink);

Remarks

The activity selects the prompt to play (such as main, silence, and escalated silence) before raising this event. This selection is based on the dialog history. The selection is available from the PromptType property on TurnStartingEventArgs.

Application developers can change the prompt by attaching an event handler to this event and providing the prompt in the event arguments.
