To work around this problem, the screen reader may implement a workaround and gathers the missing data through some other, "unofficial" channel.Let's say that for an ARIA tablist implementation, the browser does not provide the necessary information about which tab currently is active to the accessibility API: For example, the fact that a specific accessibility feature worked well in the combination of NVDA 2018.1 and Firefox 58 is no guarantee that it will still work in NVDA 2018.2 with Firefox 58 (or NVDA 2018.1 and Firefox 59). Screen readers sadly seem to be very prone to regressions, meaning that a feature which worked well in an earlier combination of browser and screen reader versions does not work anymore in subsequent versions.
So please, do not kill the messenger - instead, follow this guide and provide high quality messages! Reasons for bugs And this makes clear why the same website with the same screen reader may work well in one browser (maybe Firefox), while failing completely in another one (maybe Edge): the messenger is the same, but the message quality may vary a lot. Still, a broken message is highly prone to remain being broken.

JAWS, as a rather extreme example, even used to install its own graphic driver into the system, intercepting graphical information and applying optical character recognition (OCR) to it.

In addition to this, the code quality of website content often is bad: Irresponsible treatment results in broken messages. "Responsibly" means that all needed information is provided, so that a screen reader can announce everything in a meaningful way. Many applications neglect treating the accessibility API responsibly.

Screen readers always "sit" on top of another application (for example a web browser or PDF viewer), conveying its contents to the user through audio (synthetic speech) or braille. But it is the best we can currently provide from our years long experience with the topic. Keep in mind that we are neither browser developers nor screen reader developers, so the following information may be incomplete, biased, or even wrong in some parts. In the following article, we are trying to explain the problem of buggy screen readers a little deeper. To prevent bugs, it is best to follow established standards and best practices. Thus, screen readers often are perceived as being buggy. While this works sometimes, it often results in strange behaviours.
In addition to this, many websites are coded poorly, and some screen readers even try to compensate for this. Screen readers "sit" on top of another application, conveying its contents to the user through audio or braille.Īs many of those applications do not care too much about accessibility and present their content in non-semantical or other inadequate ways, screen readers try to compensate for this. This is a very hard task and prone to regressions, as we try to explain here. Sitting on top of another application, screen readers announce the underlying content - often trying to compensate for inadequate presentation by both the underlying application and its content. How screen readers work - and why they seem so buggy
