Plenty of certification courses are only taught in English, and so is a lot of company training. If English isn't your first language, that usually means reading captions while you try to follow a cloud console, or stopping every minute to look something up. DubMog gives you a third option: it dubs the lesson into your language while it plays.
You add a free extension to Chrome or Microsoft Edge, open the lesson, choose your language and press Start dubbing. A few seconds later you hear the instructor in your language, with the original voice turned down underneath. The translation also shows up as text in the side panel.

Why hearing it helps with technical training
In a technical course the instructor is usually doing something on screen while they talk, clicking through a cloud console or typing a command. Read captions as well and your eyes keep jumping between the subtitles and the part that matters. With the explanation in your ear, you can keep watching the screen.
Dense material is also hard to read and understand at the same time. In your own language you can keep up without pausing after every sentence.
Your language doesn't have to be on the course's subtitle list, either. DubMog works from the audio, so Pro Live can dub into more than 80 languages.
Where it works
DubMog dubs training sites whose video plays ordinary sound in the browser tab, such as Oracle MyLearn, AWS training, Cisco Networking Academy, the Fortinet Training Institute and Udemy Business, as well as Udemy, Coursera and Skool. The same goes for your company's own learning platform: if a lesson plays normal sound in the tab, DubMog can dub it.
Some sites protect their audio, and then the tab comes through silent. DubMog notices within seconds and tells you, and it won't keep spending your minutes on a silent tab. Before you decide a site is blocked, check the simple things: is the video actually playing, and is the tab muted? Standard is free, so try it on your own course first.

How to dub a training course, step by step
- Install DubMog from the Chrome Web Store, or from Microsoft Edge Add-ons if you use Edge.
- Open your course and start the lesson video.
- Click the DubMog icon in the toolbar to open the panel. Until you pin it, the icon sits in the puzzle-piece menu.
- At the top, pick Standard or Live (that's Pro Live, the natural AI voice). In Standard, set Video language to the language the instructor speaks. Then choose yours under Dub into and press Start dubbing. In Chrome, the first time you use a language pair in Standard, the button reads Install instead; it downloads that pair once (tens to a few hundred MB).
There's also a shortcut. Right-click the lesson page, choose Dub this video with DubMog, and it starts dubbing straight away. The original keeps playing quietly under the dub, and the two are easier to tell apart on headphones than on laptop speakers.
On a work laptop, IT may decide which extensions you can install, and your company may have rules about where training content can go. If the install button is blocked, ask IT to allow DubMog and tell them what leaves the computer. With Pro Live, the tab's audio goes to Google's Gemini as it plays, and DubMog doesn't keep it. Standard in Chrome keeps the audio on your computer; when it speaks with one of Chrome's built-in Google voices, the translated text (not the audio) goes to Google. Standard in Edge sends the audio to Microsoft's speech service. The extension's usage counts include the name of the site you dub, but nothing else from the page. Privacy policy →
Technical terms, labs and exam day
When a term comes out wrong
Product names, acronyms and commands are where machine translation slips most, so expect the odd mangled term. The side panel keeps every translated line with its time (press Show next to Transcript). When you want the exact word, press Stop, replay that spot to hear the instructor, then start dubbing again; stopping doesn't clear the transcript. The panel keeps your three latest transcripts until you close the browser or DubMog updates, so save each lesson's with Download .txt or Copy all before you move on.
Labs in another tab
DubMog dubs the one tab you started it on, and it keeps going while you switch to a lab in another tab, so leave the lesson open. A video inside the lab isn't dubbed. To dub that one, stop DubMog and start it again from the lab's tab.
Pausing to take notes
Pro Live's voice starts about 3 to 4.5 seconds after the instructor (a median of 3.3 seconds in our own tests). When you pause, it finishes the sentence it was on, then waits. A long pause won't drain your minutes: Pro Live stops buying time about 30 seconds after the tab goes quiet. If the tab stays quiet for about a minute and a half, DubMog stops on its own, so press Start dubbing again when you're back.
Exam day
Exams use the vendor's own wording and come in a fixed set of languages. Learn the material in yours, then go over the key terms in the language you'll take the exam in. Don't run DubMog, or any other translation tool, during the exam itself. Each exam sets its own rules about what you're allowed to use.
What a whole course costs
Standard is free: 30 minutes a day without an account, and unlimited once you make a free one. It speaks with a voice built into your browser or computer. In Chrome the speech recognition runs on your computer; in Edge it uses Microsoft's online speech service.
Pro Live is the natural AI voice, in 80+ languages, and it runs on DubMog minutes. Pro's monthly allowance counts 2 minutes for every minute of audio (the member rate), and a pack counts 3. You can hear Pro Live before you pay. The extension gives you a free 30-second taste a few times a day.
| Video to dub | Standard | Pro Live with Pro ($9.99 a month) | Pro Live with packs |
|---|---|---|---|
| A 1‑hour lesson | Free | 120 of your 600 monthly minutes | One 180-minute pack ($4.99) |
| 5 hours of course | Free | One month of Pro ($9.99) | Five 180-minute packs ($24.95) |
| A 10‑hour course | Free | Two months of Pro, 5 hours each ($19.98) | Ten 180-minute packs ($49.90) |
Pro's minutes don't carry over, so a 10-hour course in a single month is Pro plus five 180-minute packs ($34.94).
Pro costs $9.99 a month or $79.99 a year. Packs never expire, and checkout is in your local currency where available. If you'll use more than about two hours of Pro Live a month, Pro works out cheaper than packs. You can also mix the two voices, with Standard for the easy parts and Pro Live for the hard ones.

Training a team?
If your company or school is paying, DubMog Business gives each learner a seat of their own: full Pro with 800 Tokens a month, on their own account. Tokens are DubMog's minutes, and a seat's 800 Tokens buy 400 minutes of Pro Live at the member rate in the extension and the apps. The company gets one invoice with its name and VAT or tax ID. Seats start at one, at $19.99 per seat a month or $199.99 per seat a year.
A seat works today in the Chrome and Edge extension, the Web Studio, and the iPhone and Mac apps (update to the latest version). Android and Windows are coming.

Quick answers
Does DubMog work on certification and company training sites?
Yes, on training sites whose video plays ordinary sound in the tab, such as Oracle MyLearn, AWS training, Cisco Networking Academy, the Fortinet Training Institute and Udemy Business. If a site protects its audio, the tab comes through silent and DubMog tells you.
Will the dub get technical terms right?
Not always. Product names, acronyms and commands are where machine translation slips most. The side panel keeps every translated line with its time, so you can find the spot, stop the dub and replay it to hear the original term. Before an exam, go over the key terms in the language you'll take it in.
Does pausing to take notes use my minutes?
Only briefly. Standard is free, and Pro Live stops buying time about 30 seconds after the tab goes quiet, so a long pause doesn't drain your minutes.
How much does a whole course cost?
Nothing with the free Standard mode. With the Pro Live voice, five hours of course a month fit inside Pro ($9.99 a month), and one hour costs one 180-minute pack ($4.99).
Can my company pay for it?
Yes. DubMog Business gives each learner their own seat with 800 Tokens a month, on one company invoice, from 1 seat at $19.99 per seat a month or $199.99 per seat a year.
