This assortment of APIs causes inconsistency and differences with how screen readers read the web page and support the WAI-ARIA attributes on different browsers therefore, each screen reader has its recommended browser for maximum compatibility. When it comes to the web, things get even more complicated, since every browser has its accessibility API, which screen readers use to read the web page alongside the OSвЂ™s accessibility API. The problem is that each OS provides its specific accessibility API, and sure enough, you canвЂ™t find a cross-OS screen reader. Screen readers use the operating systemвЂ™s accessibility APIs to parse and read the UI to the user. Screen readers provide audio and braille output, and most of them also have visual indicators.

We will cover in a nutshell what screen readers are and how they work, as well as a few basic concepts for using them, mainly how to check that assistive technologies are conveying all the interface components as intended. It may affect many usersвЂ™ user experience.

This post is by no means intended to be a comprehensive user guide or for making you screen-readers experts, but merely to give you a tool that lets you peek into another layer of the UI you are delivering.

If you are a Windows user, check out the Windows version of this post here. In this post, I will refer to MacOs VoiceOver. I therefore thought it would be a good idea to write a short guide to essential screen reader usage to help front end developers adding it as an additional item in their self-test tool belt. TodayвЂ™s screen readers are available for all operating systems, and most (if not all) modern OSs have a built-in screen reader. To some extent, it is like developing a user interface without looking at the screen. It made me realize that many front-end developers have a blind spot of an entire aspect of the interface they are working on. This post was born when, while writing for another post, I found myself repeatedly trying to explain and demonstrate how the examples IвЂ™ve showed, affect screen reader users.
