Video elements containing audio must provide captions that convey the audio information in text format.
Captions are crucial for people who are deaf or hard of hearing, as they provide access to information presented through audio in videos. Without captions, these individuals may miss important content. Captions also benefit many others. For example, someone in a noisy café might not be able to hear the video and can rely on captions to follow along. In a quiet library, a person may choose to mute the audio and read the captions instead. Additionally, captions can assist language learners or those who process information better when both reading and listening simultaneously.

"I cannot count how many times I have felt stuck because a video I need to watch for my work does not have captions. You would think people would realize by now that not everyone can just turn up the volume. I rely on visual information so much, but without captions, it is like a whole door shuts in my face. I hate having to ask someone else to help all the time. It is not just frustrating, it is embarrassing. I am a professional, I should not need a translator to understand basic things, especially when it is critical for my business.
Just last week, I had to watch a tutorial about a new glaze technique for ceramics. The video was in English, but without captions, I could not follow the detailed instructions. I ended up having to ask one of my hearing colleagues to sit with me and explain it – wasting both of our time. It made me feel helpless, like I could not run my own studio efficiently. And it is not just about me; it is about respect for anyone who is deaf. We deserve to be able to work just like everyone else, without being constantly reminded of how we are left out."
A government website features an important video explaining how citizens should prepare and respond in case of a natural disaster, such as a hurricane or flood. However, the video lacks captions, making the life-saving information inaccessible for deaf and hard-of-hearing users.
