Accessibility has become a popular avenue for tech companies lately, and today Apple revealed its latest push: Voice Control. With macOS Catalina and iOS 13, you'll be able to control your devices completely with your voice. At WWDC, Apple showed that this can be used to do things like launch apps and select emoji thanks to a system of labels and grids. You can also ask it to simulate actions like a long press or access things typically done with swipe or gesture -- like the app switcher. Most importantly, the company says your voice is processed on the device. Nothing is sent to, or stored by, Apple.
