NonVisual Desktop Access (NVDA) is a free, open source, portable screen reader for Microsoft Windows. The project was begun by Michael Curran in 2006. The current version is still alpha software.

NVDA is programmed in Python. It currently eschews video intercept techniques in favour of working with accessibility APIs such as Microsoft Active Accessibility, IAccessible2 and the Java Access Bridge. It is licensed under the GNU General Public License.

NVDA uses eSpeak as its integrated speech synthesizer. Additionally it supports SAPI synthesizers^[1]. Output to Braille displays is supported officially from Version 0.6p3.

[edit] Integration

Besides general Windows functionality, NVDA works with WordPad, Notepad and Internet Explorer. It supports the basic functions of Outlook Express, Microsoft Word 2000/XP/2003 and Microsoft Excel 2000/XP/2003 ^[1]. NVDA was not tested with Microsoft Office 2007. The free office suite OpenOffice.org is supported to a limited extent. NVDA also supports Mozilla Firefox (version 3 or higher). Firefox is the recommended web browser for maximum barrier free web browsing by the NVDA developers.

Since early 2009 NVDA supports WAI-ARIA so that in the future web applications can be better used by blind persons ^{[2] [3]}.

Support for email is provided with Mozilla Thunderbird version 3 or higher.

In the newest release, 2010.1, NVDA supports 64 bit additions of windows, loggon screen and UAC screens, and has full support for Internet explorer. It also has a newer version of the E-speak speech synthesizer, and in the newest snapshots, video hooks are being worked on.
