Understanding YouTube Captions: Auto-Generated vs. Manual
YouTube provides two types of captions. Auto-generated captions are created by YouTube's speech recognition AI and are available on most videos in supported languages. They're surprisingly accurate — over 95% for clear speech — but can struggle with accents, technical jargon, and overlapping speakers. Manual captions are uploaded by the video creator or a professional captioner and are typically near-perfect. When you extract captions using our tool, we automatically detect which type is available and select the highest-quality track. You can see all available caption tracks and switch between them, including different languages and auto-generated vs. manual options.
