Live automatic captions are slowly being rolled out to predicted English channels with over 1,000 subscribers.
Automatic captions are shown on Android and iOS devices and on computers. To learn how to turn captions on or off, follow these steps.
After the live stream ends, live automatic captions will not remain and automatic captions will be generated based on the video on demand (VOD) process. Live automatic speech recognition (LASR) is specifically for an in-progress live stream.
Troubleshoot live automatic captions
If the stream doesn't show automatic captions, it could be due to one or more of the following reasons:
- The feature hasn’t been turned on for the channel, as we're slowly rolling out to channels with more than 1,000 subscribers.
- Channel is streaming in ultra low or low latency (such as a mobile live stream). Live automatic captions are only available for normal latency streaming.
- Automatic captions don't support the language in the video yet.
- The video has poor sound quality or contains speech that YouTube doesn't recognize.
- There are a few speakers whose speech overlaps or more than one language at the same time.
