Yes, your suggestion is much better.

Do you want the visual and programmatic included in the updated statement? The programmatic part would mean "media alternative for text" (or similar) has to be in the accessible name/desc.

Depends if "labeled" is usually understood to mean those already. Just wanted a way to clarify it if asked. A note would also work.

I do not think "clearly labeled as such" means the accessible name. I think this is a visual label or description.

This is ACT's proposed rule for Audio element content is media alternative for text. It doesn't check programmatic label..

Then should we specify "Visual" for clarity?

How about something like this in the Assumptions section for appropriate rules:

Audio-only, video-only, and synchronized media can be "clearly labeled" as alternatives for text in various ways, including text alternatives and text descriptions. At a minimum, a visual label must be provided.

#### Test Instructions
<ol id="7TI">
<li id="7TI-1">Identify the text for which the media is an alternative.</li>
<li id="7TI-2">Play the media that is labeled as an equivalent alternative for the text.
<ul>
<li>Check that the meaningful audible information of the media is available in the text.</li>
<li>Check that the meaningful visual information of the media is available in the text.</li>
</ul>
</li>
</ol>

#### Test Results
<p id="7TR">If any of the above checks fail, then the multimedia is not a media alternative for text. Perform Baseline Tests <a href="#174-test-procedure-for-captions-prerecorded">17.4 Test Procedure for Captions (Prerecorded)</a> and <a href="#175-test-procedure-for-audio-description-prerecorded">17.5 Test Procedure for Audio Description (Prerecorded)</a> on the pre-recorded synchronized multimedia. </p>

### Advisory: Tips for streamlined test processes

- Testing synchronized media is different from testing Baseline [16. Audio-Only and Video-Only content](../16AudioVideo).
- Synchronized media players may be software or HTML.
- At Level AA, SC 1.2.5 applies to synchronized media. The related Level A requirement, SC 1.2.3, should be marked as ‘Not Tested’ in the test report. It is permissible for test processes to add a test for SC 1.2.3 (evaluate a full text alternative for equivalence). Adding such a test would exceed baseline test requirements and would not affect Baseline 17’s outcome.
- All synchronized multimedia should be tested. If the pre-recorded multimedia is labeled as an media alternative for text, confirm that it provides equivalent information as text. If it does not, then it is not a media alternative for text. Test the multimedia for captions and audio descriptions
