[](https://travis-ci.org/PolymerElements/iron-a11y-announcer) _[Demo and API docs](https://elements.polymer-project.org/elements/iron-a11y-announcer)_ ##<iron-a11y-announcer> `iron-a11y-announcer` is a singleton element that is intended to add a11y to features that require on-demand announcement from screen readers. In order to make use of the announcer, it is best to request its availability in the announcing element. Example: ```javascript Polymer({ is: 'x-chatty', attached: function() { // This will create the singleton element if it has not // been created yet: Polymer.IronA11yAnnouncer.requestAvailability(); } }); ``` After the `iron-a11y-announcer` has been made available, elements can make announces by firing bubbling `iron-announce` events. Example: ```javascript this.fire('iron-announce', { text: 'This is an announcement!' }, { bubbles: true }); ``` Note: announcements are only audible if you have a screen reader enabled.
