If you say one of these numbers, that button will be activated.
One of the best commands for navigation is “show numbers.” When you say this, your screen will be filled with lots of little numbers next to any clickable buttons. This will cause a floating microphone icon to appear in the bottom-right corner of your screen. Then click the box next to Enable Voice Control. To enable this new macOS feature in Catalina, go into System Preferences, click on Accessibility, and select Voice Control from the left sidebar. With Voice Control, you can tell your computer to open apps, perform searches, scroll down a page, and, of course, dictate and edit text. Voice Control is designed for those who are unable to use a mouse or a trackpad, but it can be used by anyone.
Move over Siri, there’s a new way to talk to your computer.
