Clone Your Voice Inside Claude 📚
Connect Fish Audio to Claude, upload a 15-second clip of yourself, and get an AI voice that reads your newsletters, scripts, or anything out loud in your own voice.
A free 60-second setup with Fish Audio. Connect it to Claude, hand it a short recording of yourself, and Claude can read anything out loud in a voice that actually sounds like you, your newsletter, your scripts, your video voiceovers.
What You'll Need
This runs inside Claude Code, the version of Claude that can run commands and code for you. You point it at Fish Audio (a voice-cloning tool), give it a free API key, and hand it a short clip of your voice. From then on, Claude can generate speech that sounds like you.
Three things before you start: Claude Code open, a free Fish Audio account, and a clean 15-second recording of yourself talking. That is it. 15 seconds of your voice, about 2 minutes to set up, start to finish.
Create your free Fish Audio account first so everything is ready: fish.audio.
About "free" (read this)
Fish Audio's top S2.1 Pro model is free to use through the end of July 2026 under fair use. Even after that, Fish Audio keeps a standing free plan (around 8,000 credits a month, about 7 minutes of audio, with voice cloning), so you can keep making clips in smaller batches. If you are reading this later and S2.1 Pro is not free anymore, the steps are identical, you are just on the free plan or a paid one.
Heads up
Only clone your OWN voice, or a voice you have clear permission to use. Making a realistic clone of someone else without their consent is not okay and can be illegal. This guide is for cloning yourself.
Step 1: Connect Fish Audio To Claude
First, teach Claude Code how to use Fish Audio. This is one line. It installs the Fish Audio "skill," so Claude writes the correct voice code instead of guessing.

Step 2: Get Your Free API Key
The skill teaches Claude how to talk to Fish Audio. The API key is what actually lets it in, like a password for your account. It is free to create.
Tip: If Claude says the key is not working, paste it again with no extra spaces, and double check you copied the whole thing. Then ask Claude to "test the Fish Audio connection."
Step 3: Clone Your Voice
Now the fun part. Record about 15 seconds of yourself talking naturally, save it as an audio file, and hand it to Claude.

Step 4: Make It Read Anything
Your voice is cloned. Now put it to work. Paste in any text, or upload a document, and have Claude read it out loud in your voice.

The rules that make it work
Use a clean, quiet 15 to 30 second sample, that is what makes or breaks the clone. Copy your API key right away (it may show once). S2.1 Pro is free through end of July 2026, then it is the free plan or paid. And only ever clone your own voice.
