People with disabilities rely on interface controls that are used programmatically. These controls have a visual label, as well as a programmatic label, known as its Accessible Name. Users have a much better experience if the visible text labels of controls match their accessible names.
Speech input users can navigate by speaking the visible text labels of menus, links and buttons that appear on the screen. It’s confusing to speech input users when they say a visible text label they see, but the speech input does not work because the accessible name that is enabled as a speech input command does not match the visible label.
