Editor's Notes
- #3 Captions are text that has been time-synchronized with the audio track and appear on-screen while the video plays. They originated in the 1980s as an FCC mandate for broadcast television in the US. Captions display dialogue and describe relevant nonspeech elements like sound effects and speaker identification that are necessary to the viewer’s understanding of the video – especially if the viewer cannot hear the audio.
- #6 Captions assume the viewer can't hear and display words in the same language that is spoken in the video. Subtitles assume the viewer can't understand the language and display a translation of the spoken words and exclude non-speech sounds. Transcripts are merely the text version of the audio and are not time-synchronized with the video but are the first step to creating captions https://www.3playmedia.com/
- #7 It is important that the captions are (1) synchronized and appear at approximately the same time as the audio is delivered, (2) equivalent and equal in content to that of the audio, including speaker identification and sound effects; and (3) accessible and readily available to those who need or want them.
- #8 Can be used as a starting point. Automatically-generated captions do not meet user needs or accessibility requirements, unless they are confirmed to be fully accurate. Usually they need significant editing.

- #20 To avoid situations like these, it is important for a presenter to remember that members in the audience may have a wide variety of characteristics with respect to gender, ethnicity, race, marital status, age, communication skills, learning styles and abilities, interests, physical abilities, sensory abilities, socioeconomic status, and religious beliefs. Since the speaker is not likely to know specific characteristics of participants, it makes sense to be proactive and design a presentation that will be accessible to anyone-or, at least almost everyone-without the need for accommodations. https://www.washington.edu/doit/tips-delivering-accessible-presentation
