What is the main function of a screen reader?

• A. To change text colors on a page
• B. To read aloud text from a screen
• C. To translate web content into different languages
• D. To magnify screen content

Answer: (B)

The primary function of a screen reader is to read aloud text from a screen, enabling users, particularly those who are visually impaired or blind, to access digital content. Screen readers work by interpreting the information displayed on the screen and then converting it into synthesized speech or braille output. This allows users to navigate through applications, websites, and documents via auditory feedback. By providing spoken descriptions of on-screen elements, screen readers eliminate barriers to information and facilitate a more inclusive experience for individuals who might otherwise struggle to access visual content. While changing text colors, translating content, and magnifying screen content are valuable features for improving accessibility, they do not serve the fundamental purpose of a screen reader. The essence of a screen reader lies in its capability to verbalize text and convey information, making option B the correct answer in this context.
