An API to allow developers to trigger announcements on certain screen events and interactions. This is accomplished by adding a new HTML element aria-live and method for announcing UI changes aurally.

Use Backdrop.announce() to indicate to screen reader users that an element on the page has changed state. For instance, if clicking a link loads 10 more items into a list, one might announce the change like this.

  .on('itemInsert', function (event, data) {
    // Insert the new items.
    // Announce the change to the page contents.
    Backdrop.announce(Backdrop.t('@count items added to @container',
      {'@count': data.items.length, '@container': data.container.title}
