abbr with title
Screen reader compatibility
HTML WCAG
Nov 26, 2024
Expected Result: works in a screen reader
Actual Result: causes problems in 86 screen reader / browser combinations
Note: some screen readers have speech dictionaries mapping common abbreviations to their spoken equivalents. For example, "etc" is usually mapped to "et cetera" when spoken in NVDA and JAWS. This can give the impression the `abbr title` attribute is being spoken when in fact the speech dictionary is being used. JAWS has an 'Expand Abbreviations' setting which does read `abbr title`, but this is turned off by default and these tests use default AT settings.
WCAG Technique: H28
Code used for this test:
<p><abbr title='Three Letter Acronym'>TLN</abbr></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
