Live AI dubbing for anything playing in Chrome. ADRODUB listens to the tab and speaks the translation out loud, a real voice over the original, not subtitles.
No subscription · No credit card · Runs on your own free Google key
You miss the slide, the speaker's face, the play. ADRODUB turns the original audio down to about a quarter and speaks the translation over the top, the way live interpretation sounds on television. The balance is yours to adjust, live, while it plays.
ADRODUB runs on a key you create yourself, which is why it is free and why your audio never passes through us. You do this once.
Go to aistudio.google.com/apikey and sign in. The key icon sits in the left sidebar, labelled “Get API key”. A personal Gmail is fine.
The button is at the top of that page. Google makes the key instantly and shows it once. It starts with AIza and the account stays on the free tier. Copy it.
Click the ADRODUB icon in your Chrome toolbar. The button opens the Advanced panel with the cursor already in the right field.
The key is written to your own browser as you type and never leaves your machine. The button turns into “API key saved”, so you never enter it again.
Choose your language and press Start dubbing. In a podcast with two hosts, ADRODUB gives a man and a woman different voices by listening to the pitch of whoever is speaking.
That is not a defect, it is how interpretation works. Any interpreter, human or machine, has to hear a phrase before it can say it. You notice it at the start of a sentence and stop noticing it a minute later.
The tab's audio goes from your browser straight to Google and the translated voice comes back. We store the name and email you signed up with. We never receive or store what you listen to. The full policy is on the privacy page.
Powered by Gemini Live Translate, Google's model built for continuous real-time speech translation.
Gemini fixes one voice per session, so ADRODUB runs two sessions at once and listens to the pitch of whoever is speaking to decide which one hears them. A man and a woman get different voices. It costs the same, because the audio is split between the two rather than sent to both.
It separates by pitch, not by gender, so two speakers in a similar register will share a voice. You can also pin a single voice for anything with one speaker.
Yes. No subscription and no credit card. ADRODUB runs on your own free Google Gemini key, which is why there is nothing for us to charge for. Very heavy daily use can reach Google's free tier limits; beyond that, Google sells paid keys.
Roughly one to two seconds. An interpreter has to hear a phrase before it can say it, so some delay is unavoidable. Human interpreters work the same way.
Any Chrome tab that makes sound: YouTube, live news, Twitch, Coursera, Udemy, podcast players, recorded calls. It is not tied to one site. It cannot run on Chrome's own pages, such as the Web Store or settings.
Yes, when their voices sit in clearly different registers, which is usually the case for a man and a woman. ADRODUB detects pitch rather than gender, so two speakers who sound alike will share one voice. You can also pin a single voice instead.
We store the name and email you sign up with, and nothing else. The audio never reaches us, it goes from your browser straight to Google.
Any Google account can create one free at aistudio.google.com/apikey. Paste it once into ADRODUB; it is stored only on your own device.
Free, private, and running in about two minutes.
