Let WordPress Speak
WordPress 4.2 is shipping with a useful new JavaScript method: wp.a11y.speak(). This is a utility to make it easy for WordPress core to create consistent methods for providing live updates for JavaScript events to users of screen readers – with the side benefit that developers of plug-ins and themes can also make use of it either on the front or back end.
From Let WordPress Speak: New in WordPress 4.2 on Make WordPress Accessible.
I’m excited about this upcoming feature in WordPress and its ability to make modern, snappy JavaScript-powered pieces of WordPress a great experience for screen reader users.
