Context

NonVisual Desktop Access (NVDA) is a free, open-source Windows screen reader begun by Michael Curran in 2006 and developed since 2007 by Australian non-profit NV Access, removing the cost barrier of commercial screen readers that can cost hundreds of dollars per licence.

Results

The independent WebAIM Screen Reader User Survey #10 found NVDA the most commonly used screen reader worldwide at 65.6% of respondents (ahead of JAWS at 60.5% and VoiceOver at 43.9%), with 37.7% naming it their primary screen reader, and the highest user satisfaction of major screen readers at 97.6%.

Conclusions

As a small non-profit, NV Access depends on grants and donations (e.g. a Nippon Foundation grant) rather than licence revenue, creating less predictable funding than commercial competitors — a sustainability risk the survey data does not capture.

Implementation

Implementation detail (cost, timeline, staffing, conditions for success) is not yet available for this practice.
