People who are Deaf or who have limited hearing often rely on captions and transcripts to perceive dialogue, understand background sounds, and otherwise experience the audio track of digital media. People who are blind or have low vision may require audio description to understand what is happening onscreen. But media description doesn't only benefit people with disabilities: captions, transcripts, and audio description also provide information for people in loud or distracting environments, English language learners, people with low literacy, and others.

Recorded lectures, educational videos, podcasts, training content, videos on social media channels, and other online media should include appropriate captions, transcripts, and audio description to ensure access for all.

Core guidelines for online media

• Provide captions for all recorded media. You can obtain captions from a third-party or create captions yourself with a variety of tools.
• Ensure that captions are available whenever they are needed.
• For live meetings and webinars, provide real-time CART captions.
• Provide audio description for visual media when the onscreen activity is important to understanding the content.
• For audio-only media such as a podcast, provide a text transcript.
• If a vendor or third party is providing your media, make sure they include captions.
• Proofread your captions for completion and accuracy
• Follow best captioning practices such as speaker identification, punctuation, and additional sounds.
• If your event generates automatic captions, be sure to correct them before publishing.
