Developers must specify the current application status to the onupdatestate function to get a proper voice control from the Voice Assistant.
This function is called right before processing every utterance, so that the Voice Assistant can be aware of the application status dynamically.
Depending on the status, the callback function called could be different. Therefore, it is important to return the real status of the application.

optional VoiceApplicationState onupdatestate();

Product : TV

Privilege Level : Public

Privilege : http://developer.samsung.com/privilege/voicecontrol

Return Value :

• optional VoiceApplicationState : the status of the current application status.
  "None" : Application is in its default status. Same as "Player" status.
  "List" : The application is showing something in list.
  During this status, the utterances "Play this" or "Play" will call onselection(0).
  The utterance "Previous" will call onnavigation ("NAV_PREVIOUS").
  "Player" : The application is playing a piece of content.
  During this status, the utterance "Play this" will call onplay().

Since : 6.0

Code Example :

webapis.voiceinteraction.setCallback({
  onupdatestate : function () {
    console.log("Assistant tries to get app state");
    return "List";
  }
});

For a contents search provided by the application, it can receive a search utterance to show the search results.
In order to support the search via voice, the application must be registered to Samsung TV's companion search application and have the following callbacks.
The OnSearch parameter has a specific format. To learn more about it, please refer to the getDataFromSearchTerm.
Some callbacks are not called by default such as onsearch.
To receive all the callback signals on the development stage, request a key from Samsung and apply the key to the Manifest of your Tizen Application.
The following example shows how to add the "http://developer.samsung.com/tizen/metadata/support-vif-devfeature" key to the manifest file.
