Success Criterion 2.5.3 Label and Name *

Understanding Success Criterion: 

For user interface components with labels that include text or images of text, the name contains the text that is presented visually.
A best practice is to have the text of the label at the start of the name.

Accessibility Level: 
Intent of Success Criterion: 

The intent of this Success Criterion (SC) is to help ensure that people with disabilities who rely on visual labels can also use those labels programmatically. Controls are often labeled with visible text. Controls also have 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.
In addition, when the accessible name is different from the visible label, it essentially becomes an unknown hidden command for speech input users that can be accidentally activated without the user knowing what has happened.
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. It’s an extra cognitive load for a speech input user to remember and say a speech command that is different from the visible label they see on a control. It’s also an extra cognitive load for a text-to-speech user to absorb and understand speech output that does not match the visible label.

Specific Benefits of Success Criterion: 

• Speech input users can directly activate controls on a page with fewer surprising changes of focus.
• Text-to-speech users will have a better experience because the labels that they hear match the visible text labels that they see on the screen.
