## Definition

Auto captions are captions that speech recognition software creates from a video's audio, with no manual typing.

## Extended Definition

A speech recognition model turns spoken words into text and times each line to the audio. When a caption is labeled auto-generated, it means software wrote it and a person may not have checked it.

Accuracy depends on audio quality, accents, overlapping speakers and unusual names, so proofread before you publish. BlitzReels transcribes a video and times captions word by word, which allows word-by-word highlighting. You can correct the words before export.

## FAQ

### What does it mean when captions are auto-generated?

Auto-generated means speech recognition software wrote the captions from the video's audio. A person may not have checked them, so names and unusual words can be wrong.

### Are auto captions accurate?

Accuracy depends on the audio. Clear speech from one person usually works better than overlapping speakers, background noise or strong accents. Proofread names, numbers and brand terms before you publish.

### What is the difference between auto captions and closed captions?

Auto captions describes how the text was made: by software. Closed captions describes how it is shown: as a track viewers can turn on or off. Auto captions can be delivered as closed captions or burned into the picture.
