A free screen reader that turns Windows into a talking desktop
NVDA, for NonVisual Desktop Access, is a screen reader for Windows. It reports what is on screen through a synthetic voice and, when one is connected, a refreshable braille display, so a blind or partially sighted person can use the same computer, the same programs and the same documents as everyone else. It is developed by NV Access, a charity, is free of charge with no licence key, and is translated into dozens of languages.
What the program does
NVDA reads text, menus, buttons, list items and web content, and it moves focus around the interface in response to keyboard commands rather than the mouse. A browse mode handles web pages and documents by reading them as structured content, while focus mode passes keystrokes to forms and applications that need them. Object navigation reaches parts of a window that ordinary keyboard navigation cannot, and the speech viewer shows what is being spoken for sighted colleagues, trainers and developers. Braille output supports many display models, and an add-on store installs extensions that add support for specific applications or languages.
The working rhythm
The screen reader starts with a hotkey and then stays out of the way, announcing changes as they happen. Users learn a small set of core commands: read the current line or window, list links or headings, move by element type, and open the NVDA menu to change speech, braille or application-specific settings. Configuration profiles let different settings apply automatically in different programs. Because virtually everything is driven from the keyboard, the first days are spent learning shortcuts rather than clicking around menus.
Settings and limits
Speech comes from a synthesizer, and the built-in one is compact and responsive rather than natural sounding; other voices can be selected from those installed in Windows or added separately. NVDA is a screen reader, not a magnifier, so users who need enlargement combine it with a magnification tool. Some applications expose poor accessibility information, and reading them can require object navigation and patience. Add-ons must match the installed NVDA version, and the project ships both an installed and a portable build for use on machines you do not own.
Who should choose something else
Windows includes Narrator, which is adequate for basic tasks and is always present, so a user who only needs occasional speech may not need to install anything. Where an employer or an institution has standardised on a commercial screen reader with vendor support contracts, that choice may be made for other reasons. NVDA is the natural pick for anyone who wants a capable, actively developed screen reader without paying for it.
- Best for
- Blind and partially sighted Windows users, and the trainers, schools and workplaces that support them, who need a capable screen reader at no cost.
- Good to know
- Speech quality depends on the chosen synthesizer, NVDA is a screen reader rather than a magnifier, and add-ons must match the installed version.
How to get started
- Download the NVDA installer from the NV Access download page and run it.
- Choose the installed or the portable version, then let the installer start NVDA when it finishes.
- Press the NVDA key with N to open the NVDA menu, and read the quick-start guide from the help menu.
- Learn the core commands: read the current line, read the window, and list links or headings in a page.
- Open the speech settings to change voice, rate and pitch, and connect a braille display if you have one.
Questions & answers
Does NVDA cost anything?
No. It is free of charge, funded by donations and grants, and there is no licence key or subscription. The portable version can be carried on a USB stick.
Can I use it alongside a magnifier?
Yes. NVDA handles speech and braille while a separate magnification program enlarges the screen, and the two are commonly used together.
What is the built-in voice like?
The bundled synthesizer is clear and fast but noticeably synthetic. You can switch to voices already installed in Windows or add others for a more natural sound.
