视频和音频

Ensure that both human-edited captions are included in videos 和 audio descriptions are provided in transcripts for audio-只有 content. This ensures accessibility 和 enhances the user experience for individuals with different needs. As online experiences increasingly rely on video 和 audio formats, it's important to cater to diverse audiences by providing comprehensive accessibility features.

以满足 大学政策 需求, video 和 audio content must include text-based alternatives so all users can access the information.

视频字幕和音频转录

Video captions 和 audio transcripts provide access to people who:

  • 你是聋子还是重听
  • are learning another language, or whose native language does not match the audio content (i.e.(国际学生)
  • have learning disabilities or other cognitive impairments
  • learn by taking in information in multiple ways
  • are in quiet environments where audio output is undesirable (i.e.、图书馆)
  • are in noisy environments where audio may be difficult to hear or underst和 (i.e.,学生会).
  • do not have equipment that supports audio output (such as headphones)
  • are looking for information contained in a video; search engines can find information in captions 和 transcripts, 但不是在视频或音频文件中

音频描述

音频描述 in videos provide access to people who: 

  • 失明或视力低下
  • are learning another language, or whose native language does not match the audio content (i.e.(国际学生)
  • have learning disabilities or other cognitive impairments
  • learn by taking in information in multiple ways
  • are in visually stimulating environment where looking at the video may be undesirable (i.e.(在运动或驾驶时)

查看、编辑或请求标题

Captions are text blocks in a video that display all audio information, 包括口语作品, 听起来, 和音乐. 标题是:

  • Time-coded so two (but sometimes three) lines of text appear at a time, 通常在视频的底部
  • Either “closed” (able to be turned on or off by the user) or “open” (on all the time)
  • 以与音频相同的语言显示

副标题类似于字幕, 但它们只显示口头内容, usually in a language other than the language of the audio, 和 they can be turned on or off by the user.

Do

回顾你的视频. Do they include captions that adequately match what the speakers are saying? Are changes in who is speaking labelled, if this is not apparent in the audio? If not, replace the videos or include adequate captions.

不 assume that all videos have closed captions. 

It's crucial not to rely solely on auto-generated captions, as they may not meet the high accuracy st和ards required by individuals who 你是聋子还是重听, 通常超过99%. 另外, auto-generated captions often overlook essential non-speech elements present in the audio.

不 assume subtitles can take the place of captions

音频描述 use the audio track to describe what is happening within a video. With some planning, they are relatively easy to include while recording a new video. They can be added to existing videos by recording a narrator's voice in the natural pauses 和 silences, 但这是一种更新且昂贵的方法.

Do

回顾你的视频. Does the audio adequately explain what is happening on screen? If not, replace the videos or add audio descriptions.

Transcripts are plain-text versions of the speech or audio in a video or audio recording. Unlike captions, transcripts are not time-coded; they are static documents.

If you are sharing an audio recording, include a transcript. Each line of text should identify who said what.
