Youtube cc意思

"CC" on YouTube stands for "Closed Captions." Closed captions are a text version of the dialogue, sound effects, and music in a video, designed to benefit viewers who are deaf or hard of hearing. They can also be used by people who watch videos in a noisy environment or prefer to watch videos on mute.

When you enable closed captions on a YouTube video, you'll see the dialogue and other relevant audio information displayed at the bottom of the video. You can usually adjust the size, color, and position of the captions to suit your preferences.

To turn on closed captions on YouTube, you typically click on the "CC" icon in the video player. If the video has captions available, they will be turned on, and you can select the language if there are multiple options. If the video doesn't have captions, the "CC" icon will be grayed out, and you won't be able to enable them.

YouTube allows creators to add closed captions to their videos, either by uploading a caption file or by using YouTube's automatic captioning feature, which uses speech recognition technology to generate captions. However, the accuracy of automatically generated captions can vary, and many creators choose to review and edit the captions to ensure they are correct.
