Reflections on Teaching and Learning

Benefits of Captions

Captions are often seen as only a benefit for individuals who are deaf or hard of hearing.  This simply isn’t the case.  Captions are beneficial to a wide variety of people and situations.  For example, a person might have difficulty with hearing the audio track because of a noisy environment, not because of a hearing impairment. Additional benefits:

  • Captions can be read by people who benefit from seeing and hearing words together; this could be English language learners, people with certain learning disabilities, or visual learners.
  • In some situations, users may not be able to access audio on their computers, such as lab stations without speakers. Captions solve that.
  • Captions are searchable, allowing viewers to search media files for a topic of interest. Companies like CNET have discovered that captioning their videos increased their search engine optimization dramatically.
  • When videos have poor sound quality, captions improve communication.1
  • Captions clarify when the language is heavily accented. 1
  • When one is unfamiliar with the terminology of a subject, captions make the words clear. 1
  • Captions can be translated into other languages during playback. Purdue’s research activities could reach a larger audience with potentially greater impact for the international community.

    This is very interesting! Those of us who do not work in the assistive technology area often do not think of the impact of such efforts beyond this area. I’ve read, for instance, that making web sites fully accessible improves the user experience for everyone, not just the differently abled. Good post!

      Rob,

      Thanks for the positive feedback.

      I agree with the position that all users benefit when a web site is designed to be fully accessible. The analogy in the physical world is curb cuts. Many more people benefit from these than just users in wheelchairs. So, in the same way, everyone benefits from accessible web sites.

      Dean
