The problem it solves
You've probably heard that AI can copy a voice from a short recording. Hearing about it and hearing it in your own voice are two different things.
GemClone is a plain test bench for that. No editing software to install, and no setup beyond a free key from Google. Record yourself, clone, type a sentence, and judge for yourself how close it gets.
It's also a useful reality check. If a short clip of your voice is enough to make a convincing copy, that's worth knowing the next time someone "calls" sounding like a family member asking for money.
How it works
- Get a free Gemini key. Open Google AI Studio (there's a link next to the key box), sign in with a Google account, and create an API key. Paste it in. Tick Remember on this device if you don't want to paste it again.
- Record your voice sample. Press Record now and talk naturally for 10 to 30 seconds, or choose Use an audio file to upload a clip you already have.
- Read the consent sentence. Same person, same voice, reading the sentence shown on the page. Record it or upload it.
- Clone. Pick Flash (more expressive) or Flash-Lite (faster, cheaper) and press Clone my voice. If the button is greyed out, the page lists what's still missing.
- Make it talk. Type what you want said, add a style if you like ("cheerful" or "slow and calm"), and press play. Your original recording sits right beside it so you can compare. Use Download WAV to keep the result.
Tips for a better clone
Record in a quiet room, close to the mic, in your normal speaking voice. Aim for 20 to 30 seconds of steady talking rather than a few words with long pauses. Read a paragraph, describe your day, anything.
Use a real recording of a real person. Google rejects AI-generated or heavily processed audio, sometimes with a bare error and no explanation. If something goes wrong, the error message is copied to your clipboard so you can see what Google said.
On a phone, use the https address so the browser lets the page use your microphone.
It only clones your own voice
That consent sentence isn't decoration. Google requires a recording of the same person saying, word for word, that they own the voice and agree to a synthetic copy. Only clone your own voice, or one you have clear permission to use.
The clone also doesn't stick around. It lasts for this session only. Close the page and it's gone, and next time you clone again.
Why I ask for your email
GemClone runs between your browser and Google. Your API key and your recordings are sent only to Google to do the cloning and the speaking. They never pass through a server of mine. If you tick Remember on this device, the key is saved in this browser only. Your name and email are the only things this site keeps.
I might send you a note now and then about other free tools I build. I will never sell or give your email to anyone else.
Questions people ask
Does it cost anything?
GemClone is free. Google's Gemini key has a free tier, and any usage beyond that is billed by Google to your key, not by me.
Can I clone someone else's voice?
No. The consent sentence has to be read by the same person as the voice sample. Only clone your own voice, or a voice you have clear permission to use.
Is my cloned voice saved?
No. The clone lasts for this session only. Close the page and it's gone.
I got an error. What now?
The error is copied to your clipboard and there's a Copy error button. The usual causes are a wrong or expired key, a sample that's too short or too long, or audio Google doesn't think is a real human voice.
Does it work on a phone?
Yes, in the browser. Use the https://gemclone.dirtsimple.app address so the microphone works.
