For audio-only media, which statement is true about alternatives?

• A. Video captions alone satisfy accessibility for audio-only media.
• B. Transcripts are optional for audio-only content.
• C. A text-based transcript is provided as an equivalent representation of the audio content.
• D. Audio descriptions replace transcripts.

Answer: (C)

For audio-only media, the essential accessibility approach is to provide a text-based transcript that serves as an equivalent representation of the spoken content. A transcript captures what is said, who says it, and often important sounds or cues, giving users who are deaf or hard of hearing access to the full information. It also helps with searchability, translation, and rapid skimming, making the content usable in more contexts.

This is why the statement about providing a text-based transcript as the equivalent representation is the best choice. Video captions apply to video content and don’t address audio-only media by themselves. Transcripts aren’t optional in accessible design; they’re a standard way to ensure parity with the audio. Audio descriptions describe visual elements and don’t replace the transcript for audio-only material.
