Installing Voice-Pro: Three Days of Getting Stuck, and What Finally Worked

I make videos, and I wanted to dub them with an open-source tool instead of paying for a service, so I set out to install Voice-Pro. It ended up taking me about three days, and honestly, most of that time I was just stuck. But I did get it working in the end, and the dubbing was worth it. Here’s a plain rundown of everything that tripped me up and how I got past it, in case it saves someone else a few of those days.

I started on the wrong platform

I started on a machine with a GPU running Linux, which seemed like the obvious choice. Then I read the project’s own notes more carefully and saw it was tested on Windows, with Linux left untested. Rather than fight a setup nobody had checked, I stopped and reinstalled everything on Windows, and right away it went a lot smoother. If you’re just starting out, learn from my detour and go with Windows from day one. It saves a ton of pointless struggle.

The installer kept freezing for minutes

The next headache was the installer freezing for minutes at a time. Turns out my network was blocking some of the download sources it relied on, so it kept knocking on doors that would never open. The fix was to make it pull everything from the main package source only. For one library that was blocked completely, I just downloaded the file by hand and dropped it into place myself. On top of that, I had to add a couple of supporting tools, ffmpeg and cuDNN, that the tool expected but didn’t install on its own.

Errors with nothing to read

Even after it installed, dubbing kept failing, and the worst part was I couldn’t tell why. There was no error to read, just a tiny yellow notification that flashed for half a second and vanished. With nothing to go on, I asked Claude Code to dig out the hidden error messages and print them somewhere I could actually see them. That one change made a huge difference. Once the errors were visible, every problem after that was something I could figure out instead of guess at.

The last thing that broke, and what I learned about how the tool works

After all that, it still wouldn’t dub. I went digging through the now-visible errors and, within about an hour, found that I’d just left the Reference Audio box empty. The message read 'NoneType' object has no attribute 'read'. It makes sense once you know how the tool works. Voice-Pro uses a voice clone that has no voice of its own and copies whatever sample you give it. With no sample, there was literally nothing for it to read, so it failed. I dropped in a short voice clip, and it finally made a proper dub.

Once it was running, the tool really delivered. The dubbing worked, and cloning a voice from just a short sample was impressive enough to make the whole thing feel worth it.

Looking back, the hardest part was never the individual errors. It was just that I didn’t know how to install this kind of software in the first place, and I got stuck at nearly every step. My takeaway is that Voice-Pro pays off if you stick with it. The setup is steep and rough on beginners, but what you get on the other side is real. If you’re willing to push through the install, or lean on a tool like Claude Code to make the hidden errors visible, it’s a solid dubbing option that costs nothing. Next, I want to spend more time with the voice cloning and see how natural I can get it to sound.
