SIA-R23<audio> element content has transcript

Accessibility requirements

This rule is not required for conformance to any accessibility requirements.


Prerecorded <audio> elements must have a text alternative for all included auditory information.


This rule applies to every prerecorded <audio> element that is either playing or for which an element exists that when activated causes the <audio> element to play.


  1. The auditory information of each test target is available through a text transcript. That text transcript is visible and included in the accessibility tree, either on the page or through a link.

    A "text transcript" in the context of this rule is defined in WCAG 2 as an alternative for time based media.


This rule makes the following assumption:

  • The language of each test target can be correctly determined, either programmatically or by analyzing the content, and sufficiently understood.

Accessibility support

This rule has no known accessibility support concerns.
