Q33. DRAG DROP
You are developing a Universal Windows Platform (UWP) app named App1.
App1 can be started by using Cortana. To start the app, users must be able to say “App1 play my music” or “App1 play music”.
You need to write the Voice Command Definition (VCD) file to meet the requirement.
How should you complete the code? To answer, drag the appropriate code elements to the correct targets.
Each element may be used once, more than once, or not at all. You may need to drag the split bar between
panes or scroll to view content.

The ListenFor element has a RequireAppName attribute that specifies where the app name can appear in the voice command. The BeforePhrase indicates that users must say your app name before the command phrase.

Q34. DRAG DROP
You are building a Universal Windows Platform (UWP) app.
You need to ensure that users can start the app by using voice command in Cortana.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Select and Place:
Answer:
Explanation:
These are the basic steps to add voice-command functionality and integrate Cortana with your app using
speech or keyboard input:
1. Create a VCD file. This is an XML document that defines all the spoken commands that the user can say to initiate actions or invoke commands when activating your app.
2. Register the command sets in the VCD file when the app is launched.
3. Handle the activation-by-voice-command, navigation within the app, and execution of the command.
Box 1: Create a VCD file. This is an XML document that defines all the spoken commands that the user can
say to initiate actions or invoke commands when activating your app.
Box 2: Register the command sets in the VCD file when the app is launched.
Here’s an example that shows how to install the commands specified by a VCD file (vcd.xml).
C#
var storageFile =
await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(
new Uri(“ms-appx:///AdventureWorksCommands.xml”));
await
Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager.
InstallCommandDefinitionsFromStorageFileAsync(storageFile);
Box 3:
Once your app has been launched and the voice command sets installed, specify how your app responds to subsequent voice command activations.Example:
protected override void OnActivated(IActivatedEventArgs e)
{
// Was the app activated by a voice command?
if (e.Kind != Windows.ApplicationModel.Activation.ActivationKind.VoiceCommand)
{
return;
}
Etc.
