JAWS can function in '40 minute mode' without a license, but be aware that using 40 minute mode for software testing is against the EULA's terms. On a Windows PC, you can download JAWS for free and run the installer, which provides both audio and visual feedback.

JAWS fully supports the Windows UIA accessibility API, as well as legacy MSAA and IA2. There's also braille and text viewers, but they display a simplified view of speech output, so may not be as useful.įreedom Scientific offers a paid testing tool called JAWS Inspect with a full speech viewer (caveat: be careful relying on speech viewers). You can open a historical view of speech output by opening the speech history window with the insert + space, then H keyboard shortcut. JAWS makes its virtual cursor's focus visible by default, but there's no direct equivalent to NVDA's speech viewer. This can have the effect of a website working fine with JAWS, but not with NVDA, which sticks to the OS accessibility APIs, so JAWS may not be the best choice for baseline accessibility testing. Note: to deliver the best possible user experience, JAWS can has the ability to work around bugs in browsers or OS accessibility API limitations by reading the DOM directly. Combined with its popularity, manual accessibility testing with JAWS is a great idea. JAWS compatibility testing is often required by government contracts. Some scripts are even paid, for example Hargen Consultancy's Zoom scripts. Instead of plugins, JAWS has scripts to enhance the accessibility of 3rd party apps. External braille devices are supported over USB. Microsoft Office and Google Docs both work out of the box, and voices for over 30 languages are included. Featuresįor web browsing, JAWS works best with Google Chrome (and Microsoft Edge, now that it's also based on Chromium), although historically it's had great support for Internet Explorer. As of WebAIM’s most recent screen reader survey, released in 2021, JAWS is the second most frequently used screen reader, usurped by NVDA, with 53.7% of responses.
