Google launches Voice Access app, promises Android users hands-free control4
Google Assistant. The app is supposed to offer “more fine-grained controls than other voice commands you might use on your phone,” which makes it kind of unique.
The most important feature of the app is the option to tap buttons and controls within apps, or scroll and navigate app screens by simply using your voice. That makes Voice Access extremely useful to individuals with Parkinson's disease, multiple sclerosis, arthritis, spinal cord injury, as well as people who don't have a disability but have their hands full for whatever reason.
In order to use Voice Access to compose and edit a text message hands-free, you'll have to say “Ok Google,” while opening another app can be done with the “open” command. The app even allows users to replace parts of a text message using their voices by using commands like “delete the line” or “replace tomorrow with Saturday.”
Google's Voice Access allows Android users to take advantage of many other commands, which are available on the app's support page, so make sure to check that out.
