Overview
EarDub is a Chrome / Edge extension for people who watch videos—not people who make them. Open a foreign-language video on YouTube, Udemy, Coursera, and similar sites, tap the EarDub button in the player, and hear Chinese dubbing while it plays—no upload, download, or wait. Highlights: 1. Full-sentence translation: stitch fragmented auto captions into complete sentences, then translate with video context so names and terms stay consistent. 2. Dub sync: AI voice follows the original speaker timeline; original and dub volumes adjust separately. 3. Supports 75+ languages and 300+ AI voices, with optional bilingual captions. Use cases: English online courses and open university lectures; treat foreign video podcasts as Chinese podcasts in the background; learn a language by understanding first, then replaying the original. FAQ: Free to use? Videos with captions (including auto captions) work on every plan, including free—see https://www.eardub.com/zh/pricing ; paid plans can also dub captionless videos on supported sites. Live streams? Not a fit; best for uploaded videos.

EarDub 是一款 Chrome / Edge 浏览器插件，给看视频的人用，不是给做视频的人用。打开 YouTube、Udemy、Coursera 等网站的外语视频，点一下播放器里的 EarDub 按钮，就能边播边听中文配音，不用上传、下载或等待。功能亮点：1. 整句翻译：先把零碎的自动字幕合成完整句子，再结合视频上下文翻译，人名和专业术语前后一致。2. 配音同步：AI 语音按原说话人的时间轴播放，原声和配音音量可以分开调。3. 支持 75+ 种语言、300+ 种 AI 声音，可选双语字幕。使用场景：看英文网课和大学公开课、把外语视频播客当成中文播客在后台听、学外语时先听懂再回看原声。FAQ：免费能用吗？有字幕的视频（包括自动字幕）所有套餐都能用，包括免费版，详见 https://www.eardub.com/zh/pricing ；付费版在支持的网站上还能给没有字幕的视频配音。能用在直播上吗？不适合直播，适合已上传的视频。
