Webpages often have visible text labels. Visible text labels also have Accessible Names. Some types of users have a much better experience if visible text labels match Accessible Names.
Speech input users can navigate webpages by speaking the visible text labels of menus, links and button labels that appear on a webpage. It’s confusing to speech input users when they say a visible text label they see and the command does not work because the accessible name is enabled as a command but does not match the visible label.
An Accessible Name that is different from the visible label acts like a hidden command for speech input users.
Text-to-speech users will also have a better experience if the text they hear matches the text they see on the screen.
This issue is even more important for Speech input and text-to-speech users who also have cognitive challenges. Remembering a speech command that does not match a visible label increases cognitive load. Parsing text output that does not match the visible label also increases cognitive load.
Note that if an icon has no accompanying text its visible label is its hover text.
