Voice

Voice is another form of input on HoloLens on the Windows Holographic platform. Once you've targeted a hologram with your gaze, you can interact with that hologram by giving a voice command. The Voice Commands are very convenient for a hands-free device, such as HoloLens. You can walk around the room and just speak out what you want.

Voice Commands can be categorized into the following types:

• System Voice Commands
• Custom Voice Commands

System Voice Commands are fixed and always available. The following is a list of system Voice Commands:

• Select
• Place
• Face me
• Bigger/Smaller
• Hey Cortana, go to start
• Hey Cortana, shut down
• Hey Cortana, move <app name> here

As a developer, you can define your own Voice Commands and actions. Voice commands are implemented based on standard Universal Windows Platform (UWP) voice command patterns and the use of the Windows Holographic platform. Having implemented a custom voice command, you must have to listen for the event handler for the same Voice Commands, very similar to how general event handling works in our development.
