How do I turn on auto captions on TikTok live?

Are you asking about live as a viewer or as a creator? For viewers, you just need to tap the captions icon (usually in the bottom right corner of the screen during the live) - that should turn on auto captions right away. If you're trying to turn on captions *for your own live*, honestly it depends quite a bit on your region and your app version, but normally it's in the live settings before you start streaming.

The subtitles icon doesn't always show up in the same place depending on your app version, so it can be a pain to find sometimes! On mobile, try looking for a small button that looks like speech bubbles or written words - it might be in the bottom right but also at the top, it really depends. Once you find it, just one tap and the subtitles turn on automatically if the creator has enabled them on their end. Otherwise, it just means the live doesn't have them!
