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.

HoloLens has the inbuilt Cortana; you can take it to the next level by integrating your Voice Commands with Cortana.
