TalkBack is a screen reader that comes installed on Android devices. This article is designed to help new or novice TalkBack users learn how to test web content in mobile Chrome.
The steps to enable and disable TalkBack may vary depending on the device and software version. Go to Settings > Accessibility > TalkBack, then enable the toggle button to activate TalkBack (this may be found in Settings > Accessibility > Vision on some devices). Within the TalkBack settings you will also find the Text-to-speech settings, which allows you to adjust the speech rate and pitch for TalkBack.
In the Accessibility options you can set an accessibility shortcut by going to Settings > Accessibility > Volume key shortcut (also called “Accessibility features shortcut” on some devices) and enable the toggle button next to TalkBack. This shortcut allows us to activate TalkBack by holding down both volume buttons for 3 seconds.
To disable TalkBack, you can do a two-finger triple tap on the home button if the shortcut is enabled, or you can hold the power button until the Phone Options dialog appears then hold down two fingers on the screen until a tone plays. TalkBack can also be suspended by holding both volume buttons for three seconds. In this case, TalkBack may be resumed from notifications or by returning to the lock screen.
