Screen reader compatibility
ARIA HTML WCAG
Sep 11, 2022
Expected Result: works in a screen reader
Actual Result: causes problems in 14 screen reader / browser combinations
A much better alternative is using an ALT attribute on the INPUT type=image element.
WCAG Technique: ARIA16
Code used for this test:
<input type='image' src='1234.png' aria-labelledby='input_img_aria_labelledby'>
<span id='input_img_aria_labelledby'>this is image button aria labelled by text</span>
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
