Who Vocnu is for
Vocnu reads videos aloud in your language as they play, and voices the videos you publish into 35 languages. Each page below covers one kind of viewer or publisher: what we tested, what it costs and when another tool fits better.
Watch in your language
The browser extension voices a video as it plays, in Chrome, Brave or Edge on a computer, from €0.03 a minute.
Online courses and lectures
A voice-over in your language while a lesson plays on the course's own site. Tried on Udemy, TED and Vimeo; an hour in Standard costs €3.96 to €6.00.
News and live streams
Live news a few seconds behind the picture, and recorded reports in sync. Tried on Al Jazeera, DW, Euronews and Twitch; half an hour a day for a month in Standard costs €59 to €90.
