How DeepL is improving its accessibility
May 19 is Global Accessibility Awareness Day (GAAD). The GAAD foundation strives to ensure accessibility is integral in the development of digital products. At DeepL, accessibility is not a project, but rather an ongoing process and commitment to increasing our product usability for billions worldwide.
DeepL’s commitment to accessibility
DeepL follows the Web Content Accessibility Guidelines (WCAG) from the Web Accessibility Initiative to improve accessibility on its site pages. Some of the most pertinent guidelines we follow include:
Providing text alternatives for images
Considering screen size and font sizes
Enabling site functionalities with keyboard usage
Structuring content for easy navigation
Maintaining consistency across site pages
A significant step toward a fully accessible digital product is optimizing the web translator for keyboard usage, with no mouse required. Users can tab through navigation links and conduct translations using only keystrokes.
We also focus heavily on visual accessibility, optimizing for the use of screen readers. Screen readers such as NVDA and VoiceOver recite words from web pages to assist users in following the text and in navigating the site.
Lastly, we pay close attention to copy across product descriptions, navigation menus, and blog posts on our site. We value clear and concise language, with uncomplicated sentence structures. Our style guide includes rules such as:
Limited use of italics
Limited use of characters such as ampersands, which create difficulties for screen readers
Recent website changes have come on the heels of an important partnership with Fable, whose testing platform identified problem areas we have improved upon.
Accessibility testing with Fable Engage
Fable Engage enables teams to connect with people with disabilities remotely and on-demand to accelerate user research, design, and development. Feedback from accessibility testers provides invaluable information for companies looking to identify problems and to improve accessibility.
Fable rates digital products using the Accessible Usability Scale (AUS). The score is calculated through a series of questions answered by accessibility testers, who assess sites on compatibility with accessibility technologies, complexity of site navigation, and ease of use without outside assistance. The AUS uses a 1–100 scale, with 100 as the top rating. Since partnering with Fable, DeepL has dramatically improved its accessibility metrics. During our first test, we scored a 70. Using the test results, we got to work to improve the site, namely changing the tab order on the web translator, and clarifying button labels... in our subsequent Fable tests, we scored 90.
First, we improved the “focus-visible state” to make it easier for users who navigate via keyboard to see which element they are interacting with. The new focus state meets the AAA standards from the WCAG:
We then improved the labeling of all the translator components, both visually and for screen readers, so that anyone can identify the element they are interacting with:
Finally, we enabled translator usage at a higher zoom setting, so people who need a larger text size can have a quality translation experience:
After making these vital improvements to the site, we received promising feedback from an accessibility tester who spent time with the web translator:
“I really like this website. I’ve never used it before, but it worked really well. It was easy to tell which language was selected as a source language and which language was selected as a target language. It was really easy to find the different languages, and then change them. So, I really enjoyed this, it is an awesome website.”
These improvements are carried over into our new mobile web release, which scored an 80. We’re continuing to partner with Fable to ensure improvements over time, and that we keep raising the bar among AI companies when it comes to digital accessibility.
DeepL is continuously making site and app improvements, with the goal of achieving a global WCAG 2 standard. This standard sets specific accessibility guidelines we’ll comply with as we further develop our products. We’re currently focusing on optimizing the desktop and mobile websites for keyboard and screen reader usage.
