The Voice Commands Window

The Voice Commands Window displays the current active voice commands available for the character. The window appears when the Open Commands Window command is chosen or the Visible property of the CommandsWindow object is set to True. If the speech engine has not yet been loaded, querying or setting this property will cause Microsoft Agent to attempt to initialize the engine. If the user disables speech, the window can still display; however, it will include a text message that informs the user that speech is currently disabled.

The input-active client's commands appear in the Voice Commands Window based on the Voice Caption and Voice property settings listed under the Voice Caption of their Commands collection.

Figure 1. Voice Commands Window

The Voice Commands Window appears when the Open Commands Window command is chosen. The input-active client's commands appear in the Voice Commands Window based on the Voice Caption and Voice property settings listed under Voice Caption of the Commands collection.

The Voice Commands Window also lists the Voice Caption of the Commands collection for other clients of the character, and the following server-generated voice commands for general interaction under the Global Commands entry:

* A character is listed here only if it is currently visible.

** All loaded characters are listed.

Speaking the voice command for another client's Commands collection switches to that client, and the Voice Commands Window displays the commands of that client. No other entries are expanded. Similarly, if the user switches characters, the Voice Commands Window changes to display the commands of its input-active client. If the client is already input-active, speaking one of its voice commands has no effect. (However, if the user collapses the active client's subtree with the mouse, speaking the client name redisplays the client's subtree.)

If a client has voice commands, but no Voice setting for its Commands object (or no Voice Caption), the tree displays "(command undefined)" as the parent entry -- but only when that client is input-active and the client has commands in its collection that have Caption and Voice settings.

The server automatically displays the commands of the current input-active client and, if necessary, scrolls the window to display as many of the client's commands as possible, based on the size of the window. If the character has no client entries, the Global Commands entry is expanded.

If the user speaks "Global Commands," the Voice Commands Window always displays its associated subtree entries. If they are already displayed, the command has no effect.

Although you can also display or hide the Voice Commands Window from your application's code using the Visible property, you cannot change the Voice Commands Window size or location. The server maintains the Voice Commands Window's properties based on the user's interaction with the window. Its initial location is immediately adjacent to the character's taskbar icon.

The Voice Commands Window is included in the ALT+TAB window order. This enables a user to switch to the window to scroll, resize, or reposition the window with the keyboard.
