EarDub

Open any captioned YouTube video (including auto-generated captions), click the dub button in the player controls, and the dub plays in sync with the picture. No file uploads or editing tools.

EarDub merges caption fragments into full sentences before translating, so the AI sees complete thoughts instead of word-for-word line fragments. Translations are quality-checked and retried automatically when they fall short.

Multiple male and female voices per language, from calm narration to energetic vlog tones, with regional accents. You can switch voices mid-video and the next sentence uses the new voice.

The dub follows the video's word-level timestamps, speeds up gently (up to 1.45x) when it needs to catch up, and realigns when you seek to a different point in the video.

Independent volume sliders for the original soundtrack and the dub — keep the speaker's real voice quietly underneath for emotion and ambience, or mute it entirely.

Show translated subtitles while listening, resize them from 14 to 28 px, or hide them completely.

Dubbing starts only when you click the button, and the extension runs only on youtube.com — it never touches other tabs or sites.

Unlike YouTube's built-in auto-dubbing (limited to creator-enabled videos), EarDub dubs any video with captions, including languages YouTube can't dub such as Turkish, Vietnamese, and Chinese.
