VibeVoice by Microsoft: free local voice cloning for multi speaker podcasts

Paid voice cloning stacks up fast once you start doing long-form audio or multiple speakers. You pass a script, swap a few takes, hit limits, and the bill grows. You also upload voice samples to a remote service. If that is a deal-breaker, there is now a clean way around it.

Microsoft’s VibeVoice runs local, clones a voice from a 10 second sample, and turns a script into a podcast-style conversation. You keep drafts on your machine. It handles multi-speaker scenes and long recordings, and it embeds a safety watermark. I set it up on a laptop in under an hour and started cutting founder intros and training clips without touching a studio.

You will clone the repo, create a Python environment, and run a quick help check. This keeps everything local. No signup. If you want GPU speed later, you can add CUDA on Linux or MPS on Apple Silicon.

bash
git clone https://github.com/microsoft/VibeVoice.git && cd VibeVoice

Create a virtual env and install Python deps. I used Python 3.10. If you are on macOS or Linux, this is quick. On Windows, use PowerShell and the Scripts\Activate.ps1 path.

bash
python -m venv .venv
source .venv/bin/activate # Windows: .venv\Scripts\Activate.ps1
pip install -r requirements.txt

Verify the CLI is wired up.

bash
python -m vibevoice --help

You should see a usage block with commands for cloning from a 10s sample, generating single-speaker TTS, and multi-speaker dialog. If that shows, you are ready to feed it a short WAV and a script. Stop here if you just wanted the quick taste. Comment AI and I will send the full setup and batching tips.
