YouTube Transcripts and Accessibility

A transcript puts what is said in a video into text, which helps people who cannot hear it, cannot play it, or simply read faster than they listen. This guide covers what an AIOS Scribe transcript can and cannot do for accessibility, how to use it as a reader, and how a creator can turn it into something genuinely accessible.

What an AIOS Scribe transcript is, for accessibility purposes

It is a machine-made text version of the speech in a video. That is useful, and it is also incomplete:

• It does not say who is speaking.
• It does not describe music, laughter, applause or other meaningful sounds.
• It does not describe what is shown on screen.
• It can contain errors, particularly with names, jargon and overlapping voices.

So it is a good starting point, and a reasonable aid for a viewer, but on its own it is not a complete accessible alternative to a video.

If you are a reader or viewer

• Read instead of listening. The Full Text view is the whole transcript as running text. The Timestamps view breaks it into short lines, each with a time that links to that point in the video.
• Find the part you need. The transcript search highlights matches and steps through them with the keyboard (Enter for next, Shift+Enter for previous).
• Use your own tools. The transcript is ordinary text on the page, so screen readers, browser zoom and your own text size and contrast settings apply to it. You can also download it and open it in whatever reader you prefer.
• Take care with the details. Because it is machine-written, double-check numbers, names and anything you will act on against the video.

If you publish videos

The Web Content Accessibility Guidelines (WCAG) set out what accessible video needs. For pre-recorded video, the relevant criteria are 1.2.1 to 1.2.5 and 1.2.8: captions, audio description, and a text alternative for the whole of the media. Whether a particular transcript meets them depends on its accuracy and completeness, and a raw machine transcript generally needs a human to review and complete it before you rely on it. This is general information, not legal advice; the blog looks at the legal landscape and why auto-generated captions are not enough.

Turning a draft transcript into an accessible one

1. Generate a draft. Transcribe your video and download it as a text or Markdown file.
2. Correct it against the video. Watch with the text open and fix every mistake, especially names and technical terms. AIOS Scribe does not edit transcripts, so do this in your own editor.
3. Add speaker names where more than one person talks.
4. Add important non-speech sounds in square brackets, such as [applause] or [phone rings], when they matter to understanding.
5. Describe what matters visually when something shown is not also said: a chart, a demonstration, a slide of text.
6. Add headings at topic changes, so that the transcript can be navigated without reading all of it.
7. Publish it with the video on the same page, in text a screen reader can read, not in an image or a PDF scan. If you are the video's owner, you can also upload the corrected text as captions in YouTube Studio.

Limits

AIOS Scribe will not make a video accessible by itself. It saves the slowest part, typing out the speech, and leaves the judgement parts, which are accuracy, speaker identity, sounds and visuals, to a person.
