näytönlukeija

A näytönlukeija, or screen reader in English, is a software application that enables visually impaired or blind users to interact with a computer. It reads aloud the text displayed on the screen, including menus, icons, and the content of documents and web pages.

Screen readers typically work by interpreting the graphical user interface (GUI) and converting visual information into synthesized speech or braille output via a connected braille display. They allow users to navigate the operating system, launch applications, and perform various tasks without needing to see the screen.

Key functionalities of a näytönlukeija include reading text, announcing dialog boxes and notifications, and providing commands for interacting with on-screen elements. Users can often customize the speech rate, pitch, and voice, as well as set up keyboard shortcuts for common actions.

Popular näytönlukeijat include JAWS (Job Access With Speech), NVDA (NonVisual Desktop Access), and VoiceOver (built into Apple devices). These tools are essential for digital accessibility, ensuring that individuals with visual impairments can access information and participate fully in the digital world. Their development and integration into operating systems and applications have significantly improved the usability of computers for a wide range of users.
