Ambiguous language defining Audio Description in Understanding 1.2.5

[gmjellin]

A common misinterpretation of 1.2.5 that I have noticed among accessibility professionals is that a separate Audio Description Track is required to narrate visual content, when in fact, the Audio Description may be included in the main (and only) soundtrack.

If my understanding is correct, "Audio Description" (AD) is narration that describes relevant information in the video content (information about actions, characters, scene changes, on-screen text, and other visual content.) AD may be part of the main soundtrack, or a separate track.

Some of the language on Understanding implies that the AD must be a separate track (in addition to the main audio track). For example, the first line of the Note (green box) in the "Intent" section states, "For 1.2.3, 1.2.5, and 1.2.7, if all of the information in the video track is already provided in the audio track, no audio description is necessary". To me, the phrasing "no audio description is necessary" seems to be conflating AD with a separate audio track.

Another example, from the first line of the "audio description" definition in the "Key Terms" section states, "narration added to the soundtrack to describe important visual details that cannot be understood from the main soundtrack alone". This language is ambiguous to me in that it states "...added to the soundtrack..." followed by, "main soundtrack alone". This implies that there are 2 soundtracks (soundtrack and main sound track).

I think it would be very beneficial to very clearly define Audio Description as the narration that may be included in the primary soundtrack or in a separate soundtrack.

#2441 is a valid issue. The Understanding pages or Techniques pages need to spell out known valid techniques for newcomers to the topic.

It's well established by precedent that a single audio track can suffice for 1.2.3 and 1.2.5. Audio description in a single (not separate) audio track is often called open audio description.

We should further clarify two methods of meeting 1.2.3 and 1.2.5 with a single audio track.

The first method is to have a narrator just for audio description, interleaving snippets of audio description into the audio track. Example: like the existing example "movie with audio description" in Understanding SC 1.2.5, clarify that this method is valid for both open audio description and closed audio description.

The second method is to have a speaker who describes the visual content while voicing the primary narrative. This has been called integrated description. Example: A trainer narrates a prerecorded training video. One of the training slides depicts a three-step process: "Plan," "Create," "Deliver." The trainer says: "Our process is to plan each project, create the content, and deliver it. It's important not to skip the planning step!"

In method 2, the trainer has "added" audio description in the sense that she made sure to convey the visual content through her narrative. However, it's not important whether we call method 2 a type of "audio description" or (from the normative WCAG definition and informative notes) a case of "all of the video information is already provided in existing audio." Either way, method 2 meets WCAG 1.2.3 and 1.2.5.

Issues currently in the Understanding SC 1.2.5 page:

• As @gmjellin correctly said: "Some of the language on Understanding implies that the AD must be a separate track."
• There is no example of method 2 of meeting 1.2.3 and 1.2.5.

[mitchellevan]

Scoping this issue:

• The present issue (2441) is to clarify whether and how a single audio track can satisfy 1.2.3 and 1.2.5.
• Not to be confused with How to add audio descriptions to videos? #1768, which seeks to clarify the distinction between 1.2.5 and 1.2.7.

I mention this because the concurrent WAI-IG thread touches on both of these issues questions.

I will volunteer to suggest an edit to understanding to help clarify the WCAG use of the term Audio Description. The WCAG use of the term is different than Video Description or how the term is used in the arts and audio-video industry. In those fields, AD is always on its own distinct audio track, or requires a different version.

if all of the information in the video track is already provided in the audio track, no audio description is necessary

I agree that is confusing. Really, it is that no additional narration is necessary to meet the (WCAG) definition for Audio Description. The note in the definition does better (emphasis added):

Where all of the video information is already provided in existing audio, no additional audio description is necessary.

Or maybe even:

if all of the information in the video track is already provided in the audio track, then audio description is already being provided

That is is awkward! Please be encouraged to suggest something better.

[mitchellevan]

How about this:

• In the "Intent" section, Note 1, add the word "additional"
• In the "Examples of Success Criterion 1.2.5" section, replace the current single example with three examples:
  • A secondary audio description track ("closed audio description")
  • Audio description in the primary audio track ("open audio description")
  • Video information already provided in the primary audio track ("integrated description").

I thought it would be hard to find an example of open audio description, but in fact the current WGBH example would suffice! Videos are broken in the original link. I found the same or similar video here: https://www.pbslearningmedia.org/resource/tdc02.sci.life.evo.chenpdr/teaching-evolution-case-studies-bonnie-chen/

Thanks @mitchellevan ! Here is another great resource I have meaning to add to 1.2.5 Understanding:

WAI does a wonderful job of delineating the differences for types of audio description in their page about description of visual information. I would recommend including the same or similar language in the "Intent" section of 1.2.5:

[Audio] description explains visual information needed to understand the content. (For example, “Pat opens a small box, looks at a diamond engagement ring, and cries”.) Depending on the type of video and media player, [audio] description can be:

• integrated into the main script and recording
• narration added to the main audio track and provided in an alternative version of the video
• provided in a text file or as a separate audio track

I also like the idea of defining open and closed audio descriptions as @mitchellevan stated.

However, for the utmost clarity, and due to the AV/arts industry norm of audio description generally meaning a separate track, changing the 1.2.5 normative statement as well to include the note (which I have changed a bit):

"if all of the information in the video track is already integrated or provided in the audio track, no additional audio track is necessary"

would probably make things clearest.

[bruce-usab]

@silverli — just to be totally candid, I am not inclined to suggest an edit to the SC notes unless there is something wrong/incorrect/terrible.

if all of the information in the video track is already integrated or provided in the audio track, no additional audio track is necessary

That seems to imply that providing AD narration in a separate additive audio track is a possibility. (And I believe that has been experimented with, but is not implemented anywhere.) How about:

if all of the information in the video track is already integrated into and provided by the audio track, no additional audio description is necessary

I am also thinking about a stand-alone sentence that the norm in the AV/arts industry is for AD to be distinct separate track, and is similar to how a movie on a DVD might provide the feature of a choice of languages.

[gmjellin]

@mitchellevan love this, particularly the terminology of open/closed desc.

In the "Examples of Success Criterion 1.2.5" section, replace the current single example with three examples:

• A secondary audio description track ("closed audio description")
• Audio description in the primary audio track ("open audio description")
• Video information already provided in the primary audio track ("integrated description").

@silverli, I think that language from WAI would be a perfect addition to the 1.2.5. It articulates the main options for including AD very well and it is consistent with WAI, which is always nice.

[Audio] description explains visual information needed to understand the content. (For example, “Pat opens a small box, looks at a diamond engagement ring, and cries”.) Depending on the type of video and media player, [audio] description can be:

• integrated into the main script and recording
• narration added to the main audio track and provided in an alternative version of the video
• provided in a text file or as a separate audio track

@bruce-usab I agree that the term AD is often used to mean a distinct separate track, and it even seems to in the 1.2.5 Intent/Key Terms/Examples (though not entirely explicitly). @mitchellevan That is why I do agree with @silverli that the use of the term Audio description in the SC text

Audio description is provided for all prerecorded video content in synchronized media

is problematic because it is AD is widely understood to mean a distinct separate track. I think many who read the SC with that understanding of the term conclude that the SC does indeed require a separate track. I realize changing the SC text is a big deal and I think it is acceptable to solve the ambiguity with the other clarifying language in the Understanding doc.

I really appreciate everyone's effort and ideas here.

[awkawk]

I don't agree with the suggested change - it impacts the definition of audio description and will create further confusion. When a video contains all of the information about the visual aspect that is needed to understand it in the primary program audio, no AD is needed. That's why the definition for audio description has the note: Where all of the video information is already provided in existing audio, no additional audio description is necessary.

There is also a note in the understanding document that reads: For 1.2.3, 1.2.5, and 1.2.7, if all of the information in the video track is already provided in the audio track, no audio description is necessary.

What is the actual problem that people are trying to solve?

[silverli]

@bruce-usab As long as audio description is defined clearly somewhere, I agree, I think the normative success criteria doesn't have to change, however, changing it would aid the most people because I know that many many people out there do think audio description means a separate track, and do not read the fine print of the "Understanding" sections (but that's another problem, I suppose). I also like your edits to the note:

If all of the information in the video track is already integrated into and provided by the audio track, no additional audio description is necessary

And like your idea here:

I am also thinking about a stand-alone sentence that the norm in the AV/arts industry is for AD to be distinct separate track, and is similar to how a movie on a DVD might provide the feature of a choice of languages.

@awkawk I agree with @gmjellin about the ambiguity of the definition of AD in 1.2.5, so this is my write-up/restatement (after also discussing further with @gmjellin) of how I understand the issue we're discussing here:

WCAG 1.2.5 makes the normative statement that “Audio description is provided for all prerecorded video content in synchronized media,” however, it also says right below in the non-normative notes section that “if all of the information in the video track is already provided in the audio track, no audio description is necessary.” So it's saying both that audio description must be provided, but also that audio description is unnecessary “if all of the information in the video track is already provided in the audio track.” But the normative statement is the one which holds the most weight as the required rule. The definition of audio description becomes ambiguous and the two statements seemingly conflict (saying AD should be provided in the normative statement, but then in the notes that it can also be unnecessary). It then becomes a bit of a mental scramble to figure out what “audio description” means, or how it could perhaps mean two things in this context: both integrated audio which contains sufficient description of the video, and also audio as a separate track.

[gmjellin]

@awkawk, The crux of the problem as I see it is that many people (A11y pros and others), interpret this SC to mean that a separate AD track is required for all synchronized media. I am currently a company that sells a product that has thousands of synchronized media (videos). They are running up against potential customers who are claiming that the product is not compliant with 1.2.5 and can't purchase the product until every video has a separate AD track. I've run into similar version of this problem at least half a dozen times.

If the SC had language that didn't include AD, but instead stated something like, "Narration describing important visual details is provided for all prerecorded video content in synchronized media" (imperfect perhaps, but bare with me), then the Understanding document would largely be fine as is with some tweaks.

Because the SC uses the term AD, which to some is defined as narration describing important visual details that may be included in the primary (integrated) soundtrack or a separate track in addition to the primary track, but to others is defined as narration describing important visual details in a separate track in addition to the primary track, there is frequent confusion as to whether a separate track is required or not.

I agree that if you spend enough time reading and rereading the Understand doc (at least for some of us with perhaps marginal comprehension) it can be understood as it is intended to mean that the narration is included in the primary track or a separate track. However, I can promise you from personal experience, way too many people are not able to grasp that and it is causing a lot of confusion.
