Yesterday I asked “What’s the most up-to-date info on aria-live regions (and

) support in AT?” for some client work I’m doing. As usual, Twitter was responsive and helpful.

Heydon replied

Should be fine, support is good for live regions. Not sure about output, though … Oh, you’re adding the p _with_ the other XHR content? That will have mixed results in my experience.

I’ve seen some failed announcements with live-regions on VoiceOver, especially with iframes. (Announcement of the title seems to kill any pending live content).output has surprisingly good support but (IIRC) is not live by default on at least one browser (IE, I think).

Some more resources people pointed me to:

• ARIA live regions explainer doc on MDN
• On Demand Live Regions A tiny module for making screen readers announce text on demand, without a visual change to the interface, by Heydon Pickering
• output: HTML’s native live region element – Use role="status" to bridge some gaps in browser/ AT support of <output>
• Accessibility Support Will your code work with assistive technologies?
