LidubChrome extension for YouTube
Watch YouTube in Vietnamese
Lidub is a Chrome extension that dubs YouTube videos into Vietnamese as you watch: it reads the video's subtitles, translates them and speaks them in a Vietnamese voice that stays in sync with the picture. Built for English–Vietnamese first.
- Chrome 116 or newer
- Works right on youtube.com
- Sign in with Google
How it works
From subtitles to a Vietnamese voice, right in your browser
-
Subtitles
The extension reads the video's subtitles inside your own browser. Lidub's servers never access YouTube.
-
Translate
Subtitle lines are split at punctuation and translated into Vietnamese; lines someone has already translated are reused, so they load faster.
-
In-sync Vietnamese voice
The voice is timed to each line, and the original audio is lowered while it speaks.
Highlights
Open a video as usual, turn on Lidub, and hear Vietnamese

Privacy
The extension only runs on youtube.com and sends lidub.com the subtitle text it needs to translate and voice. Only when you turn on listen mode yourself is the audio of the video you are watching sent for speech recognition.
Lidub does not read your browsing history or your YouTube account, and does not sell data. When you sign in with Google, Lidub stores your name and email to manage your account and usage budget.
