NVDA

NVDA (NonVisual Desktop Access) is a free, open-source screen reader for Windows that reads on-screen text, menus, and controls aloud using synthesized speech or sends the output to a refreshable braille display. It is widely used by people who are blind or have significant vision loss as a no-cost alternative to commercial screen readers like JAWS. Because it is free and runs from a USB drive without installation, it is a practical first screen reader for many users and a common choice in schools and lower-budget settings.
