Captions are text that have been synchronized with media (usually video) to convey meaning, context, and any information that is integral to the understanding of a video. Closed captions do more than convey spoken words, but should convey sounds, noises, and background elements as well. In short, closed captions assume that the listener cannot hear any of the content and captions seek to provide an understanding of the content without the need for audio. Many video production tools now incorporate speech recognition systems to produce automatically generated closed captions.
This particular page will share written tips, screenshots, and a video tutorial for utilizing automatic closed captions, auto-translated captions, and improving the display of automatic closed captions in YouTube. Teachers can utilize the tips on this page when delivering instructional content to students or for showing students how they are able to make their own video viewing experience more accessible.
Closed captions benefit a variety of learners in many ways. Firstly, some learners require access to closed captions (CC) as part of individualized education plans (IEPs). This is a legal requirement teachers must fulfill. However, in addition to supporting students with IEPs, closed captions ensure full, equal access to audio content by providing written text of what is being said or text descriptions of any noises that provide context in audio or video. Certainly, captions can help support students deaf and hard of hearing students, however, English Language Learners can also benefit from closed captions. Roughly 1 in 10 students in the United States is an English Language Learner-about 4.5 million students! Closed captions can help clarify video content and boost understanding if technical terms are used in the video, sound quality is poor, speakers in the video have accents, or if the environment around the learner is too noisy to listen. Automatic closed captions are helpful in scenarios where the teacher (or viewer) is not the owner of the video file and cannot provide accurate, updated closed captions, but needs captioning as an option. Though automatic closed captions are not perfect, they are a helpful option.
Essentially, closed captions provide another means for viewers to understand video other than relying on the video's audio alone. There are many ways to provide closed captions for videos in educational contexts, whether the video has been created by the teacher or borrowed from another source.
YouTube contains speech recognition systems to automatically create closed captions for all videos uploaded into the platform. Thus, by default, any instructional video you upload to YouTube and any instructional video you access from YouTube (perhaps not a video you uploaded yourself) will contain automatically generated closed captions. While this is a helpful feature for consistently providing some level of accessibility, speech recognition technology is based upon machine learning algorithms that are constantly evolving, thus the quality of captions varies.
To use automatic closed captions, follow the steps below, the images at right, or the tutorial video.
Visit YouTube.com and open a video.
Hover your cursor over the video and select the "CC" button to turn on closed captions. If the user has uploaded professional captions, those captions will play as priority over automatic closed captions. If the user has not uploaded captions, automatic closed captions will be displayed when the video plays. Pressing the "C" button on the keyboard also acts as a keyboard shortcut to turn on closed captions. Press the CC button to turn off the captions or enter the C button on the keyboard.
The display, opacity, size, and language of the captions can be adjusted using the video's settings menu. Click the "Settings" cog.
Select "Subtitles/CC" from the settings menu.
To have captions translated into another language, select "auto-translate" and then select the language. Note that because auto-translations also use machine learning systems, there may be discrepancies.
To adjust the size, opacity, and color of the closed captions, click the settings cog once more, select "Subtitles/CC" and then select "options".
In the options menu, configure the font style of the captions, font size, font color, background color, opacity of the captions, and more.
Click play on the video (or press the spacebar) and the adjustments to the closed captions will go into effect. The viewer can re-adjust the captions as needed through the settings menu.
