Audio-only content has transcript; videos have audio descriptions for important visual information

Audio-only content—podcasts, voice announcements, audio guides—is entirely inaccessible to deaf users without a transcript. Video content that conveys information through visual actions (screen recordings, code walkthroughs, data visualizations) is inaccessible to blind users without audio descriptions narrating what is shown. WCAG 2.2 SC 1.2.1 (Level A) requires transcripts for audio-only content; SC 1.2.3 (Level A) requires audio descriptions or transcripts for prerecorded video. Section 508 2018 Refresh 503.4.1 incorporates these. A podcast series or tutorial library with no transcripts excludes an entire class of users from the site's core value proposition.

Provide a transcript link adjacent to every audio player. For inline transcripts, render them in a collapsible section directly below the player:

<audio controls src="/audio/episode-12.mp3" />
<details>
  <summary>Read transcript</summary>
  <div className="transcript">
    <p><strong>Host:</strong> Welcome to episode 12...</p>
    <p><strong>Guest:</strong> Thanks for having me...</p>
  </div>
</details>

For screen-recorded tutorials with no narration of visual actions, either: (a) re-record with audio descriptions narrating every on-screen action, or (b) provide a step-by-step written alternative linked next to the video. Store transcript files in public/transcripts/ and link them with descriptive anchor text: <a href="/transcripts/episode-12.txt">Download Episode 12 transcript (TXT)</a>.
