Requirement

area link to sound file must have text transcript.

Error

area link to sound file may be missing text transcript.

Short Description

area elements must not contain href attribute values that end with (all case insensitive) .wav, .snd, .mp3, .iff, .svx, .sam, .smp, .vce, .vox, .pcm, .aif

How To Determine

Question Is there a text transcript associated with this link to a sound file?
PASS Link to sound file has an associated text transcript.
FAIL Link to sound file does not have an associated text transcript.

Steps To Check

Procedure

1. Check the alt attribute value of each area element.
2. Check if the alt attribute value ends with a sound file suffix.
3. Following is a sample list of sound file suffixes. This is not an exhaustive list and the author should test the actual file to determine if it is a sound file: .wav, .snd, .mp3, .iff, .svx, .sam, .smp, .vce, .vox, .pcm, and .aif.
4. If the alt attribute value ends with a sound file suffix then check the content for a link to a sound file transcript.

Expected Result

1. If the area's alt attribute links to a sound file then the content is expected to contain a link to a text transcript for the sound file.

Failed Result

1. Create a text transcript of the sound file and add a link to it.
