TikTok Captions vs Subtitles: What's the Difference?
People use the words "captions" and "subtitles" interchangeably — but they mean different things, especially when it comes to accessibility and video production. Here's a clear breakdown of what each term means on TikTok and when to use each.
Captions vs Subtitles: The Core Difference
Designed for viewers who cannot hear the audio. Captions include ALL audio content: spoken words, sound effects ("door slams"), music descriptions ("[upbeat music]"), and speaker identification. Captions serve deaf and hard-of-hearing audiences.
Designed for viewers who can hear but don't understand the language. Subtitles translate or transcribe only the spoken words — no sound effects or music descriptions. Subtitles serve viewers watching in a foreign language.
Closed Captions vs Open Captions on TikTok
Open Captions
Burned into the video itself — always visible, cannot be turned off. Common in TikToks where the creator manually adds text overlays. These are permanent and travel with the video wherever it's shared.
Closed Captions
Optional text layer that viewers can turn on or off. TikTok's Auto Captions feature generates closed captions. These can be toggled by the viewer in the TikTok app settings.
TikTok Auto Captions — How Accurate Are They?
TikTok's Auto Captions feature uses speech recognition to generate captions automatically. Accuracy varies significantly — typically 70-85% for standard English speech, and lower for accents, technical terms, or fast speech.
For higher accuracy — especially for content you're repurposing or sharing on other platforms — use our free transcript tool. It uses OpenAI Whisper, which achieves 95-99% accuracy and provides downloadable SRT, VTT, and TXT formats.
