What do screen readers do in library technology?

• A. A tool that translates text into foreign languages.
• B. Software that converts digital text into speech or braille, enabling access for visually impaired users.
• C. A program that blocks pop-up ads.
• D. A device that prints braille only.

Answer: (B)

Screen readers are a form of assistive technology used in libraries to give visually impaired users access to digital content. They work by taking the text that appears on the screen and converting it into speech, or into braille on a refreshable Braille display. This enables users to listen to catalogs, ebooks, articles, and websites, and to navigate interfaces with spoken cues and structure. The other options describe functions that don’t match what screen readers do—translation into another language, blocking ads, or printing braille—so they don’t fit. The important idea is that screen readers transform on-screen text into an audible or tactile form to make content accessible without needing to see the screen.
