Vocnu for training videos
Your team hears the training you already have in its own language, without re-recording it, and you pay by the hour of video. HR uploads a video once in the Vocnu app and gets it back with a voice-over and subtitles to publish where the training lives, or each employee turns on the Vocnu extension while the training plays in the company's own player. An hour of training in Standard quality costs €3.96 to €6.00 a language. On 10 November 2026 a ten-minute software tutorial came back in Polish and in Spanish for 11 credits each, in under ten minutes. Vocnu does not clone the trainer's voice, match lips or let you edit the script.
Uploads run in the web app in your browser, with nothing to install.
Upload once, or let each employee turn it on
| What matters | HR uploads the video | Each employee uses the extension |
|---|---|---|
| Who does the work | One person uploads each video once and publishes the result | Each employee installs Vocnu and turns it on while the training plays |
| Where it plays | Your LMS, intranet or video host, as a new video file | The page where the training already plays, in Chrome, Brave or Edge |
| Phones and tablets | Yes: it is an ordinary video file | No: the extension runs on a computer |
| What it costs | Once per video and language | Per employee, for the minutes each one watches |
| Who can check it first | A colleague who speaks the language, through a share link | Nobody: each employee hears the translation as it is made |
For a whole team, uploading is cheaper. If 20 employees each watch an hour of training with the extension in Standard, that comes to 1,200 credits; uploading the same hour once costs 60. The extension suits one person who needs a video now, or a video HR cannot upload, such as a vendor's course on its own site.
A ten-minute tutorial in Polish and Spanish
On 10 November 2026 we uploaded a 10 minute 28 second English screencast on using Phabricator, a project management tool, and asked for Polish and for Spanish in Standard quality.
- Each language cost 11 credits, €0.73 to €1.10, and each finished in under ten minutes.
- Each came back as a WebM video with the voice-over as its main audio and the English original as a second track, with subtitle tracks in both languages, plus the voice-over alone as M4A, the subtitles as SRT, VTT and ASS files and the English transcript.
- The English transcript heard the tool's name as "fabricator" eight times, yet both translations wrote "Phabricator" all eight times. Polish even declined it: "A task in Fabricator defines some work to do." became "Zadanie w Phabricatorze opisuje pracę do wykonania.", and in Spanish "Una tarea de Phabricator define un trabajo que hay que hacer."
- Asking for an MP4 instead of the WebM we uploaded raised the quote to 22 credits a language: the app re-encodes the picture for it, at the rate of burned-in subtitles. Keep the format you upload, or upload an MP4.
The video is "Phabricator - Tasks" by AKlapper (Wikimedia Foundation), dedicated to the public domain under CC0 on Wikimedia Commons; the voice-overs and subtitles were added by Vocnu.
Video players we tried the extension on
Company training usually plays in an LMS, an intranet page or an embedded player rather than on YouTube. These are the closest we have tested:
| Player | Tested | Translated from | First line after |
|---|---|---|---|
| The video player of a wiki, Wikimedia Commons, into Polish | 10 November 2026 | The video's English subtitle track | 13 seconds |
| A plain MP4 file open in the browser, on the Internet Archive, into Lithuanian | 10 November 2026 | What it heard: the file has no captions | 68 seconds |
| A YouTube video embedded in a blog post on the Chrome for Developers site, into Lithuanian | 8 November 2026 | The uploader's English captions | 39 seconds |
We have not tested an LMS such as Moodle, Docebo or Cornerstone, so try one of your own videos with a new account's 40 free credits before you count on it. Some company computers only allow extensions IT has approved; Vocnu installs from the Chrome Web Store. The MP4 was "His Girl Friday" (1940), in the public domain, from the Internet Archive.
What a training library costs
| Quality | An hour, one language | An hour, five languages | Good for |
|---|---|---|---|
| Standard | €3.96 to €6.00 | €20 to €30 | Most internal training: clear voices and a good translation |
| Premium | €7.92 to €12 | €40 to €60 | Videos dense with product or legal terms |
| Economy | €1.98 to €3.00 | €9.90 to €15 | A large archive where a plain synthetic voice will do |
The prices run from the largest credit pack to the smallest. Each video's minutes are rounded up, so our 10 minute 28 second tutorial was billed as 11 minutes. You see the price before a job starts and never pay more than that quote. Subtitles burned into the picture, for a player that shows no subtitle files, add 1 credit a minute, and SDH subtitles, which also write out sounds and speaker names, add 1 credit.
Translate a training series
- Sign in to the Vocnu app and upload one video of the series you own or may translate.
- Choose the language, Standard quality and a video with voice-over, and keep the format you uploaded. The app shows the price before anything starts.
- When it is ready, send its share link to a colleague who speaks the language. They can play it and download its files without an account, until you turn the link off.
- If they are happy with it, download the video, or the voice-over audio and the subtitle files if your LMS takes them separately, and publish it beside the original.
- Translate the rest of the series the same way, and keep the files in your own system: Vocnu deletes uploads after 7 days and finished files after 30.
If the trainer's voice under the translation distracts, turn the original sound off before you start; the video then holds the new voice and silence between its lines.
Product demos and short clips
The same upload works for a product demo or an onboarding clip, but short clips are billed by the started minute, so the seconds matter:
| Clip | Billed as | Credits in Premium |
|---|---|---|
| 22 seconds, our test on 10 November 2026 | 1 minute | 2 |
| 1 minute 1 second | 2 minutes | 4 |
For social feeds that start muted, burn the subtitles in, or upload the SRT or VTT file where the platform takes one. If nobody speaks in a screen recording, the app tells you before you start and voices the text on screen instead; we have not tried that on a training video yet, so start with a short one.
When Vocnu is not the right pick
- The trainer on camera should keep their own voice, or their lips should match the new language. Synthesia and HeyGen offer voice cloning and lip-sync in 130+ and 175+ languages, by their own sites as we read them on 10 November 2026, and Rask AI is compared in Vocnu vs Rask AI. Vocnu does neither.
- The wording must be approved line by line, as in safety or compliance training. Vocnu has no editor for fixing a line before it is voiced, so have a person translate it.
- The slides, quizzes and LMS pages need translating too. Vocnu changes what is said and adds subtitles; the text in the picture and around the video stays as it was.
- Several trainers talk and each should sound different. One voice reads every speaker.
