We also tested NVDA with the full version of Outlook. We tested NVDA and Thunder with Microsoft's Outlook Express mail client, as well as with Web-based e-mail using AFB's Outlook Exchange system. We compared the performance of the two products in the following eight categories of computer use: We evaluated the speech output performance of NVDA and Thunder on several different Windows 7 and XP computers. You can download Thunder and learn more about it at the Thunder website. For this project, we used Thunder version 2.021. The documentation makes no mention of the screen reader's compatibility with refreshable braille displays, and it's not an open-source screen reader. Similarly, the Thunder screen reader is free, provides feedback via synthetic speech, and is compatible with Windows 7, Vista, and XP. You can download NVDA and learn more about it at the NVDA website. For this project, we used NVDA version 2011.1. Since NVDA is an open source application, interested parties can contribute to the screen reader's improvement and development.

It's compatible with Windows XP, Vista, and Windows 7, and is also compatible with refreshable braille displays.

NVDA is a free, open-source screen reader that provides feedback via synthetic speech. Read on for our findings and conclusions. (Although we AFB TECH lab rats think very highly of Serotek's SA To Go and System Access screen readers, they were not a part of this study.) For this project, we compared the performance of NVDA and Thunder on several of today's common computer tasks. RNIB asked us to compare the performance of NonVisual Desktop Access (NVDA) and Thunder, two free screen readers for Windows computers.

This article summarizes the results of a project conducted in the AFB TECH lab at the request of the Royal National Institute of Blind People (RNIB) in the United Kingdom.
