YuJa - (All Users): Captions

This article walks you through the captioning features in YuJa.

Benefits of Captioning

Under the Americans with Disabilities Act: "The ADA requires public entities to take the steps necessary to communicate effectively with people who have disabilities, and uses the term “auxiliary aids and services” to refer to readers, notetakers, sign language interpreters, assistive listening systems and devices, open and closed captioning, text telephones (TTYs), videophones, information provided in large print, Braille, audible, or electronic formats, and other tools for people who have communication disabilities." 1

 However, there are benefits to closed captioning to all users:
  • Users are able to view the spelling of discipline specific terminology.
  • Increased comprehension and improves performance.
  • ESL students benefit when reading comprehension is better than auditory comprehension.
  • Users in a quiet environment when they can not listen to the audio without headphones. (e.g. Library).
  • Users viewing the video in a loud environment (such as the cafeteria) can benefit when they cannot use headphones.

Generating Captions

YuJa will automatically caption your audio and video files upon upload/record process. It is strongly recommended that you review your captions for accuracy. While YuJa has a 90% accuracy rate, in may not capture technical terms, words due to poor audio quality, words that sound similar, accents, and slurred speech. The "Find and Replace" and the "Caption Confidence Score" will help you in editing. Jump to:
