Definition
Auto captioning is the process of automatically generating text captions from spoken audio in a video using AI speech recognition, without manual transcription.
Auto Caption explained
Auto caption technology uses automatic speech recognition (ASR) models to convert spoken words into timed text overlays. Modern auto caption engines achieve 95%+ accuracy in English and support 50+ languages. The generated captions include word-level timing for animated text effects like word-by-word highlighting. Auto captions are essential for accessibility (deaf/hard-of-hearing viewers), engagement (85% of social media video is watched without sound), and SEO (search engines can index caption text). BlitzReels auto-generates captions with word-level sync across 50+ languages and offers 30+ visual styles for the caption overlay.
