What is the primary function of the NVDA software?

The primary function of NVDA (NonVisual Desktop Access) software is to serve as a screen reader. It enables individuals with visual impairments to access and interact with the information displayed on a computer screen by converting text to speech or providing Braille output. This essential tool reads out the elements of the user interface, such as text, buttons, and links, allowing users to navigate digital content effectively. NVDA is designed specifically to enhance accessibility by providing auditory feedback, making it crucial for tasks such as reading documents, browsing websites, and using various applications.

In contrast, the other choices—word processors, browsers, and spreadsheets—are application types that may include features for different purposes, but they do not fundamentally perform the role of a screen reader. These applications can host NVDA, but they are not designed to provide the specialized functionality of converting text into speech or making content accessible for visually impaired users.
