What is feeddub?

FeedDub is a Chrome extension that dubs videos into your own language directly inside the player you already use. It works on YouTube, Netflix, Bilibili, TED and Coursera, speaking translated lines on the original timing while keeping the original audio audible underneath. It supports 20 languages with male and female voices, and uses speech recognition when captions are unavailable.

How to use feeddub?

Install the extension from the Chrome Web Store (or manually load the ZIP via chrome://extensions with Developer mode). Open a video on a supported site, then click the microphone button in the player to start dubbing. Choose your dubbing language and voice from the popup. Two new videos a day are free without signing in; sign in with Google for three unlimited days, or subscribe for $2 a month for unlimited videos.
