Screen reader compatibility
ARIA HTML WCAG
Nov 26, 2024
Expected Result: works in a screen reader
Actual Result: causes problems in 58 screen reader / browser combinations
Note: The ARIA Text Alternative Computation allows objects to be labelled by items hidden by CSS
WCAG Technique: ARIA10: Using aria-labelledby to provide a text alternative for non-text content
Code used for this test:
<embed aria-labelledby='embed-aria-labelledby-id' type='video/mp4' src='small.mp4' width='100' height='100'></embed>
<p id='embed-aria-labelledby-id' style='display:none'>This is ARIA-LABELLEDBY text</p>
Reliability Trend
This graph shows reliability over time for this code in NVDA, JAWS and Voiceover. Other screen readers don't have enough historical data yet to plot trends.

Test notes
All tests were carried out with screen reader factory settings. JAWS in particular has a wide variety of settings controlling exactly what gets spoken.
Screen readers allow users to interact in different modes, and can produce very different results in each mode. The modes used in these tests are:
- Reading Content read using the “read next” command in a screen reader
- Tabbing Content read using the “tab” key in a screen reader
- Heading Content read using the “next heading” key in a screen reader
- Touch Content read when touching an area of screen on a mobile device
In the “What the user hears” column:
- Commas represent short pauses in screen reader voicing
- Full Stops represent places where voicing stops, and the “read next” or “tab” or “next heading” command is pressed again
- Ellipsis … represent a long pause in voicing
- (Brackets) represent voicing that requires a keystroke to hear
