Principle 2 Operable · Guideline 2.5: Input Modalities
2.5.3 Label in Name
The visible label must be part of the accessible name.
What this means in practice
Otherwise speech control fails: saying “Submit” does nothing if the button is internally named “Send form”. Put the visible text at the start of the aria-label – or skip the aria-label.
Normative wording
The binding text lives at the W3C. What you read here is our own faithful rendering – not a quotation.
