Facebook announced Voice Commands for the Oculus Quest last year. The original version, however, proved to be inconvenient. In order to access voice commands, you had to manually select the tool from the Oculus menu each and every time you wished to use it. This new update streamlines the process, allowing you to activate voice commands by saying the phrase ‘Hey Facebook’, followed by a specific command.
Facebook knows that users are going to have concerns, which is why ‘Hey Facebook’ is strictly an opt-in experience. You’ll still be able to use Voice Commands without having to say the wake word. To do that, you just use your controller or hand tracking to navigate to the home menu and then to the Experimental Features panel. From there you can then turn off the ‘Hey Facebook’ feature, giving you a little peace of mind.
