What type of information does a screen reader relay?

A screen reader is a crucial accessibility tool designed to convert on-screen content into spoken word or braille output, primarily for individuals who are blind or have low vision. The correct answer highlights that a screen reader relays text, links, and other elements in an understandable format, which is key to providing an inclusive experience for users.

Screen readers can identify various types of content, such as text, images (by relaying alternative text descriptions), and interactive elements (like buttons or forms). They read out the content in a meaningful way, ensuring that users understand the context and purpose of the information presented. This capability allows users to navigate websites and applications effectively, accessing vital information that they otherwise might not be able to perceive.

In contrast, while images and other media can be described by screen readers if provided with alternative text, the primary function of the screen reader revolves around conveying structured text and interface elements, making them comprehensible for navigation and interaction. Other options focus too narrowly on specific content types that a screen reader does not solely handle. For instance, video and audio descriptions are part of broader accessibility considerations but are not the main focus of a screen reader's functionality.
