If there is only one “Add to cart” button on the page, tools like Dragon Naturally Speaking will correctly target the button because it doesn’t need the complete accessible name to be spoken. The trouble is that someone using a speech recognition tool will not be able to see the accessible name for the button, only its visible label – which makes it difficult for them to accurately target the button using a voice command. This can seem like a good way to provide meaningful accessible names for screen reader users, whilst presenting a shorter label for the button to sighted people. The accessible name for this button is “Add Chamukos tequila to cart”, not “Add to cart” because the ARIA overrides the HTML. It can be used to provide an alternative accessible name for an element. The aria-label attribute takes a string as its value. The aria-label and aria-labelledby attributes work in different ways, but the important thing to remember is that ARIA trumps all the accessible name provided with the native HTML will be overridden by the accessible name provided with ARIA. The accessible name for an element can be altered using ARIA. This creates an association between the two elements that instructs the browser to expose the content of the label as the accessible name for the checkbox. The for attribute on the and the id attribute on the share the same value. The accessible name for the following checkbox is “Chamukos tequila”. The accessible name for a form control can be derived from an associated element. The accessible name for the following link is “Chamukos tequila £40”. When a link contains both an image and some text, the two combine to form the link’s accessible name. When an image is the only content of a link, the image’s alt attribute gives the link its accessible name. These two sources for an accessible name can be combined. The accessible name for the following image is “Chamukos tequila”. The accessible name for an image is derived from the alt attribute.

So someone using a speech recognition tool would say something like “Click chamukos tequila link”, and a screen reader would hear something like “Chamukos tequila link” when they move focus to it. The accessible name for the following link is “Chamukos tequila”. The content of an element gives the link its accessible name. The accessible name for an element can be derived from the element’s content, an attribute, or from an associated element. For example, someone using a speech recognition tool can target the element using its accessible name, or someone using a screen reader will hear the accessible name announced as they moved focus to that element. It is the piece of information used by Assistive Technologies (AT) to identify the element. The accessible name for a HTML element is exposed in the browser’s accessibility tree. It can be derived from different sources, and browsers use an algorithm called the Accessible Name and Description Computation to figure it out. Many HTML elements have an accessible name.
