While heuristics improve the user experience with non-compliant code, they also mean that JAWS hides non-compliances that would show up with NVDA. NVDA is recommended if you plan to use it to assist with a Web Content Accessibility Guidelines (WCAG) audit since JAWS uses more heuristics than NVDA. NVDA on the other hand is a free open-source software available for Windows users. JAWS is only available as a paid software, either as an enterprise package or single-use licenses ($90 a year, roughly $900 as a one-time purchase). That said, let’s take a look at some of the differences between these two popular screen readers. So when comparing, one must know that it all comes down to user preference. JAWS is arguably more popular, but NVDA has recently gained recently ground. However, i t’s important to note that no one screen reader can be said to be the best as most people who are blind use different screen readers for different purposes.įor instance, NonVisual Desktop Access (NVDA) is more language-agnostic than Job Access With Speech (JAWS). To interact with a screen reader, a user must use a set of gestures and keyboard commands and these commands are sometimes unique to the screen reader.Īccording to the result of a 2021 survey published by WebAIM, people with disabilities are more likely to use JAWS or NVDA as their primary screen reader. Using screen readers, people with vision loss can perceive, operate, and understand visual input from software, websites, mobile applications, or documents through audio output. Common examples of assistive technology are screen readers and braille displays.
Assistive technology is a software application that helps individuals with disabilities to improve their daily productivity.
