How do I make my audio and video accessible?

For external recordings, like podcasts, the following steps should be taken to assess the audio and create a transcript.
- Was the audio posted by the copyright holder? If so, a transcript may already exist. If one cannot be easily located, the copyright holder should be contact about creating a transcript.
- If the audio was not posted by the copyright holder, you should go through eReserves to obtain a copyright-compliant version of the audio.
- If the audio cannot be obtained through eReserves, it may be worth considering the educational value and need of the audio recording. Is there another way of sharing the information with the students?
- If you determine that no transcript exists and no accessible alternative can be found, the Instructional Technologist team will work with you to have a transcript created.
Transcripts can be posted as downloadable PDFs or as separate, linked Canvas pages, but they should be placed in the immediate context of the audio for easy access.

Captions vs Subtitles
Captions are an accessibility tool that many people are familiar with, but it is important to note the difference between captions and subtitles. Subtitles are simply a running transcript of the dialogue that is occurring on-screen. Captions are more encompassing and include a description of any audio that is necessary to understand the information.
For example, imagine that you are discussing time management and distractions in an office environment, and want to show your students a clip of a woman at her desk who is being bombarded by ringing phones, people talking off-screen, computer alert noises, etc. For viewers without hearing impairments, the scene is easy to understand. For viewers who are unable to hear the sound effects, however, the woman’s reactions to the noise will make little to no sense. However, if you are recording a lecture video and a dog barks outside, you don’t need to mention that in the captions—the barking is not part of the lecture and conveys no information.
One of the most common questions we get about captions on videos is if the faculty are responsible for providing captions or transcripts of external videos– that is, videos created by someone other than the faculty. This can include movie clips, expert lectures, and so on. When working with external video clips like this, faculty should work through the following steps:
- Was the video posted by the copyright holder? If so, the video may already be captioned. If the video isn’t captioned, it may be worth contacting the copyright holder about captioning.
- If the video was not posted by the copyright holder, you should go through eReserves to obtain a copy of the video clip.
- If the video cannot be obtained through eReserves, it may be worth stepping back and considering the value of the video. What is its purpose in the course? Could the same information be conveyed through another, more accessible video?
- Finally, if you have determined that there are no alternatives to the video and no way to obtain a captioned version, the SPS Instructional Technologists can submit the video to a transcription service to produce a transcript, which can be linked on the page with the video.
Please note that YouTube’s auto-generated captions are absolutely not an acceptable form of captioning on a video. While the technology is improving, it is in no way equivalent to human-created captions. To understand why, watch this clip of Bill Gates talking about online learning with the sound off and the auto-generated captions on.
Doesn’t make much sense, does it? For hearing impaired students, auto-generated captions are about as useful as having no captions at all. Videos need accurate captions that provide the same information as the audio does.
Many faculty also create videos throughout the quarter–weekly wrap-ups, announcements, etc. Ideally, these would all be scripted, and those scripts would be the base for the creation of transcripts and/or captions. Short of this ideal, however, faculty should consider the following:
- Do the videos contain academically important information?
- If so, is the academically important information available elsewhere (in text format) on the website?
For example, if a video includes information about one of the assigned readings, but that information is also included in the weekly overview, then captions or a transcript for an ad-hoc recording are less important. If the academic information in the video cannot be accessed by students in any other way, however, then a transcript is required.
