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 frameworks 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. 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. NVDA was not tested with Microsoft Office 2007. The free office suite OpenOffice.org can be operated quite successfully. NVDA supports Mozilla Firefox (version 3 or higher) very well. Firefox is the recommended web browser for maximum barrier free web browsing.

ARIA is supported by NVDA so that in the future web applications can be better used by blind persons ^[1].

Support for email is provided with the upcoming Mozilla Thunderbird version 3.
