What is Screen Reading Software?
Screen reading software is a type of assistive technology that helps visually impaired or blind individuals to access and use digital content on computers, laptops, and mobile devices. It works by:
- Reading aloud the text displayed on the screen using synthetic speech.
- Describing icons, buttons, menus, and documents.
- Helping users navigate websites, applications, and operating systems using keyboard commands.
Screen readers convert visual elements into audio (or sometimes Braille with a Braille display), enabling a person to interact with their device without needing to see the screen.

- Keyboard shortcuts for fast navigation.
- Support for different languages, including Hindi and other Indian languages.
- Ability to read:
- Documents (MS Word, PDF)
