1.2.3 Audio Description or Media Alternative (Prerecorded)

음성 해설 또는 미디어 대체 수단(사전 녹화)

Summary

Visual information not conveyed in the soundtrack needs audio description or a full text alternative. Think on-screen figures, unnarrated text, or a silent demonstration. At Level A either option works; Level AA (1.2.5) requires audio description specifically.

Common failures

  • Leaving narration like "click this button" with no audio description of what is on screen.
