Képernyolvasóalapú, or screen reader-based, refers to a category of assistive technologies designed to enable individuals with visual impairments to access and interact with digital content. These tools convert text and other visual elements on a screen into audible descriptions, allowing users to navigate and understand the information presented. Screen readers typically work by using text-to-speech software to read aloud the content of the screen, and they can also provide additional information such as the names of buttons and other interactive elements.

The most commonly used screen readers include JAWS (Job Access With Speech) for Windows, NVDA (NonVisual Desktop Access) for Windows, and VoiceOver for macOS and iOS devices. These tools can be customized to suit individual preferences, including adjusting the speech rate, volume, and voice type. They also support various keyboard commands to navigate the screen, read text, and interact with applications.

Screen reader-based technologies are essential for individuals with visual impairments, as they provide an alternative means of accessing information that would otherwise be inaccessible. They are also valuable for users with learning disabilities, cognitive impairments, and those who prefer auditory learning. The development and improvement of screen readers continue to be an active area of research and development, with ongoing efforts to enhance their functionality and usability.
