In plain language
What a control SAYS on screen must be part of what it's CALLED for assistive tech.
Who it affects
Voice-control users and screen-reader users who depend on spoken names matching visible text.
How to check
Inspect controls with visible text: the accessible name must contain that exact visible text. Worked example — A streaming music app's search results: compare the visible label to the accessible name character by character: if the label text is broken apart, reordered, or interrupted by injected hidden words, it fails matching.
Common misconception
An aria-label that adds *extra* context beyond the visible label is fine. The failure is when the aria-label replaces the visible words entirely, so voice-control users saying the visible label get no match. Real example: on a crowdfunding platform's campaign page, the name announced to screen readers is different from the label printed on the control — voice-control users say the visible label ('Click Search') and nothing happens.
