Start NVDA now

Your free screen reader

NVDA is short for NonVisual Desktop Access. It is a screen reader which enables blind or visually impaired people to access information on a computer. On-screen information is being read out and translated into Braille, a dot based tactile script. NVDA is bundled with eSpeak, a free speech synthesizer but it also is possible to use SAPI4 and SAPI 5 speech engines, like RealSpeak’s Emily. For Braille output with NVDA, Handy Tech Braille displays are ideal.

You can use NVDA right away or install it on your PC.

Starting NVDA now, you will gain immediate access to this PC. No program is installed and once you finished your session the used computer storage will be free again.

In case a Handy Tech Braille display is connected to the computer, information will immediately show on the Braille display.

Note! From the NVDA Version 2011.3 onwards, prior installation of a Braille driver no longer is necessary.

Install NVDA on your computer and you can set it to automatically start once Windows starts. It also will then be possible to start NVDA using hot keys and it will remember your individual settings.
