Voice Access provides voice commands in three categories:
Basics and navigation from any screen (e.g. "go back", "go home")
Gestures to interact with things on the current screen (e.g. "click next", "scroll down")
Text editing and dictation (e.g. "type hello", "replace coffee with tea")
You can access on-screen help by saying "What can I say?" within Voice Access. You can also see the full list of voice commands by going to Voice Access Settings and selecting "Show all commands."
The tutorial introduces the most common voice commands (starting Voice Access, clicking, scrolling, basic text editing, and getting to the "What can I say?" menu).
To stop Voice Access, just say "stop listening". To disable Voice Access completely, go to Settings > Accessibility > Voice Access and turn off the switch.
Microphone: Voice Access uses the microphone to let you speak voice commands.
Phone: Voice Access observes the phone state so it can operate during phone calls.
Accessibility Service: Because this app is an accessibility service, it can observe your actions, retrieve window content, and observe text that you type.
