Why it works
Built to not break.
Engineering
Audio ready before the cue hits
Pre-fetches the full caption track before playback begins. When a line arrives, the audio is already rendered. No lag. No desync.
Audio
Original audio underneath
Ducks the original track to 15% while dubbing plays, then restores it. You still hear the speaker's tone — no muting, no silence.
Voice quality
Auto-routed to the best engine
YTDub picks OpenAI for the 15 voice-tested majors, Azure neural for 70 more languages, browser TTS for the rest. No settings to tweak. It just picks right.
