Slide23Audio Description
Terrill ThompsonTechnology Accessibility SpecialistUW-IT Accessible Technology Services (ATS)tft@uw.eduhttp://uw.edu/accessibility/video
Slide24Which videos are the highest priority?
As with captioning, need to prioritize Videos that are required viewing for students who need description (an accommodation)Videos that are likely to be required viewing for students who need description Videos that:
Are popular
Provide critical content
Slide25Multiple Methods of Producing Audio Description
Separate "audio described version" of the video Human-narrated description Description narrated using synthesized speech A WebVTT description file Plain text, easy to produce Description is read aloud by screen readers The standard method, using HTML5 <track>
Currently only supported in Able Player
A second, user-selectable, audio track
Uses one method for all audio tracks (e.g., audio description, director's cut, translated/overdubbed)Supported in JW Player and Video.js (but not in all browsers; depends on HLSV4 support)
Slide26WebVTT

Slide27How can we create our own WebVTT description track?
Simply use your favorite text editor (e.g., Notepad)Use any captioning tool Amara.org Dotsub.comNCAM Caption and Description Editing Tool (CADET)http://ncamftp.wgbh.org
/cadet/
Slide28Captioning Tool Example
Shown: Amara.org
Slide29Which method should we use? (continued)
If dramatic work:Outsource for human-narrated descriptionLink to the "Described version" Else if need for description is minimal and simple:If using Able Player: Do It Yourself! Create a WebVTT fileElse:
Outsource for human-narrated description
OR
text-to-speechLink to the "Described version"
Slide30Which vendors provide human-narrated description?
"Services Involved with Audio Description"http://www.acb.org/adp/services.html List of 75+ providers In Spring 2017, narrowed the list to 18 providers that seemed to provide relevant services, contacted each by email or web formPrices vary significantly, based in part on complexity of the description ($12 - $75/min.)Turnaround: 24 hours – 6 weeksFinal list: 8 providers

Slide31Eight audio description vendors
Human-Narrated ($12-15/min)Access USAAudio EyesCaption Max Mind's Eye Audio ProductionsValerie H Productions
WGBH Media Access Group
Synthesized Speech ($10/min)
3PlayMedia Automatic Sync
Slide32If using 3PlayMedia, which voices/speeds are best?
Research: Three students who use descriptionWatched 9 versions of two short videos Voices: Michael, Allison, Kate (British)Speeds: Slow, Medium, Fast Watched 7 additional videos, described with various settings Results: Male/female voice should be distinct from voice of speaker(s) in video
Slight preference for Medium Michael
Slight tendency to dislike the fast voices,
especially Fast Kate.
Slide33How can we deliver a "described version"?
Add a link: "Available with audio description"Use Able Player Supports multiple versions of a video (described vs non-described); user can toggle using "Description" buttonSupports text-based audio description, announced by screen reader; user can toggle using "Description" button
