Audio & videoNot just YouTube
Not subtitles

No subtitles. Just listen.

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.

Subtitle tools
  • Read the captions that already exist, so nothing to read means nothing to translate
  • Often YouTube only
  • Subscriptions up to $129 for heavy use
  • Your eyes stay on the text
ADRODUB
  • Translates the actual audio, live, whether captions exist or not
  • Any audio or video playing in Chrome
  • Free, you bring your own free Google key

Setup, about two minutes

Set it up once. Two minutes.

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.

Play any audio or video and press start

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.

The honest part

The voice runs one to two seconds behind.

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.

Powered by Gemini Live Translate, Google's model built for continuous real-time speech translation.

Two hosts, two voices

Two speakers, two voices.

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. It is automatic, with nothing to choose.

Free stays free. Pro removes the setup.

Dubbing on your own Google key is free forever and always will be. Pro is for people who would rather not deal with keys at all, and it adds the tools built on top of what you dubbed.

Questions people ask.

Is it really free?

Yes, and it stays that way. You get one minute to try without signing up, and ten minutes once you do, both on our account. After that, add your own free Google Gemini key and dubbing is unlimited at no cost. The paid plans, from $9.90 a month, are only for people who would rather skip the key entirely.

How far behind is the voice?

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.

Which sites does it work on?

Any audio or video playing in Chrome: 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.

Does it really give two podcast hosts two voices?

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. It happens on its own; there is nothing to set up.

What happens to my email?

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.

Where do I get a Gemini key?

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.
