Trusted Tester

A standardized approach for manual inspection of Web content for conformance with the Revised Section 508 Standards.

16. Pre-Recorded Audio-Only, Video-Only, and Animations

Pre-Recorded Audio Only

Identify Content

Identify all pre-recorded audio-only content.

EXCLUDE any audio-only content that:

If there is no such content, the result for the following test ID(s) is DOES NOT APPLY: 16.A.

Note:

Check 1.2.1-audio-transcript-text

Test Name Test ID Test Condition
1.2.1-audio-transcript-text 16.A A text-based alternative is provided for audio-only content that provides an accurate and complete representation of the audio-only content.
Applicability:

This Test Condition DOES NOT APPLY (DNA) if there is no pre-recorded audio-only content.

How to Test:
  1. Determine if, for each audio-only content, a transcript is provided.

    1. Determine whether each transcript is text, (i.e., an image of a transcript would not be sufficient to pass this test).
  2. Play the audio-only content entirely while reviewing the transcript.

  3. Determine whether the information in the transcript is an accurate, correctly sequenced, and complete representation of the audio-only content.

    1. To be a complete representation of the content, the transcript must also describe relevant sounds in addition to dialogue, such as doors banging, sirens wailing, identification of speakers in dialogue, etc.
Evaluate Results:

If ALL of the following are TRUE, then the content PASSES:

  1. A text-based transcript is provided for all audio-only content, AND

  2. The transcript is an accurate and complete representation of the audio-only content.

Pre-recorded Video

Identify Content

Identify all pre-recorded video-only content.

EXCLUDE any video-only intended as a media alternative for text if it is clearly labeled as such.

If there is no such content, the result for the following test ID(s) is DOES NOT APPLY: 16.B.

Note:

Check 1.2.1-video- alternative-equivalent

Test Name Test ID Test Condition
1.2.1-video- alternative-equivalent 16.B The video-only content information is also available through an equivalent text or audio alternative.
Applicability:

This Test Condition DOES NOT APPLY (DNA) if there is no pre-recorded video-only content.

How to Test:
  1. Determine whether a text or audio alternative is provided for all video-only content (such as a transcript in text that provides a description of video content and actions or an audio track).

Note: An image of a transcript does not meet this requirement.

  1. Play the video-only content entirely while reviewing the text or audio alternative.

  2. Determine whether the information in the text or audio alternative includes the same information that the video-only presentation displays (e.g., if the video includes multiple characters, the alternative must identify which character is associated with each depicted action).

Evaluate Results:

If ALL of the following are TRUE, then the content PASSES:

  1. A text or audio alternative is provided for all video-only content, AND

  2. The text or audio alternative is an accurate and complete representation of the video-only content.
