When including video or audio content in PowerPoint, ensure you include a text equivalent via captions or transcripts.\r\n

Who closed captions and transcripts benefit<\/h2>\r\nStatistics suggest 4-5% of the general population experience some form of hearing loss or are Deaf. The number of individuals with hearing loss increases to around 20% for people over age 60. Captions and transcripts are essential for some audiences.\r\n\r\nHowever, 80% of 18 to 25-year-olds regularly use captions when watching video.[footnote]Youngs, \"Young viewers prefer TV subtitles, research suggests\"<\/a>[\/footnote]. Educators should consider that captions aid comprehension, focus, and memory[footnote]\"More than 100 empirical studies document that captioning a video improves comprehension of, attention to, and memory for the video.\" - Gernsbacher, \"<\/span>Video Captions Benefit Everyone\"<\/a>[\/footnote] and that <\/span>90 percent of all students who use closed captions find them helpful for learning.[footnote]Mary Ellen Dello Stritto and Katie Linder, <\/span>\"A Rising Tide: How Closed Captions Can Benefit All Students\"<\/a>[\/footnote]. Captions ensure names, terminology, and complex terms are communicated exactly as intended.<\/span>\r\n\r\nConsider the following video as an illustration of why captions are important. Note: ensure captions are turned on and do not adjust the volume on your device.\r\n\r\nhttps:\/\/mediaspace.langara.ca\/media\/t\/0_qq60y53t\r\n

How to ensure videos have closed captions<\/h2>\r\nUncaptioned videos are unfinished. Caption your content using YouTube<\/a>, Kaltura<\/a>, or OneDrive<\/a>. Machine-generated captions must be edited for accuracy. When using others' videos and audio\u00a0choose captioned content<\/a> and audio with attached transcripts.\r\n\r\nFor inserted videos (added via Insert > Video > This Device...<\/strong>) and audio files you must attach a caption file in .VTT format. To do so:\r\n
    \r\n \t
  1. Select the video on the slide.<\/li>\r\n \t
  2. Move to the\u00a0Playback <\/strong>tab.<\/li>\r\n \t
  3. Select\u00a0Insert Captions > Insert Captions.\r\n<\/strong>\"\"<\/li>\r\n \t
  4. Choose .VTT file.<\/li>\r\n<\/ol>\r\nInserting a video file into PowerPoint will increase the overall file size significantly. Consider embedding videos from OneDrive instead. First, add captions to videos on OneDrive.<\/a> The video will have captions when embedded in PowerPoint.\r\n\r\nTo embed a OneDrive video:\r\n\r\nGet a sharing link from OneDrive by navigating to the video and choosing\u00a0Share\u00a0<\/strong>>\u00a0Copy link.\r\n<\/strong>\"\"\r\n\r\nIn PowerPoint:\r\n
      \r\n \t
    1. Move to the\u00a0Insert<\/strong> tab.<\/li>\r\n \t
    2. Select\u00a0Video<\/strong> menu.<\/li>\r\n \t
    3. Choose\u00a0Online Video.\r\n<\/strong>\"\"<\/li>\r\n \t
    4. Paste the URL of your OneDrive\/SharePoint hosted video\u00a0and select\u00a0Insert.<\/strong><\/li>\r\n<\/ol>\r\nFor audio files, consider adding the transcript to a later slide or as an additional document distributed alongside the presentation file. Make a note adjacent to the audio recording indicating where the transcript is available.\r\n\r\nLearn more about how to create and edit closed captions.<\/a>\r\n\r\nRead how to add closed captions or subtitles to media in PowerPoint.<\/a>\r\n

      How to add transcripts to audio<\/h2>\r\nWhen adding an audio recording to PowerPoint, ensure you include a text transcript of the audio. The best method is to link to the transcript, either in an external resource or at the end of your PowerPoint slides.\r\n

      Double Check<\/h2>\r\n\"\"Missing audio or video subtitles<\/strong> will appear under\u00a0Warnings<\/strong> in the Accessibility Inspection Results. While it is essential videos be captioned and audio have a text transcript, this result is categorized as a warning because PowerPoint cannot determine if a video has no sound and therefore does not require captions or if an audio file has a transcript included later in the presentation or in a linked secondary document. Additionally, PowerPoint does not have the capability to check if an embedded video from YouTube or OneDrive has captions. The\u00a0Missing audio or video subtitles<\/strong> warning is a reminder to check media for captions and transcripts.\r\n
