TalkBack is a built-in screen reader developed by Google that serves as an important assistive technology for people who are blind or visually impaired. It converts visual information on a smartphone or tablet into spoken words, sounds, and vibrations, allowing users to interact with their devices without needing to see the screen.

When TalkBack is turned on, the device provides spoken feedback for everything on the screen, such as text messages, buttons, notifications, and apps. It also uses touch gestures and vibration to guide users while navigating the phone.

Instead of seeing the screen, users can hear and interact with it through voice prompts and special gestures.
