Voice Control, one of the many features introduced with Apple’s iOS 13 software update, gives users the ability to navigate their iOS devices with just the sound of their voice.

Commands include phrases like “swipe left,” “take a photo,” or “scroll down,” but Apple also allows users to add their own vocabulary to the feature.

Adding custom words and phrases to Voice Control can be essential for those with disabilities, and according to Apple, will make it easier for those who “work with specialized apps or documents.”
