RVC AI Tutorial: How to Clone Voices for Free on Your PC (2025 Guide)

Paid AI tools are convenient, but they get expensive. If you have a decent computer and a bit of patience, you can clone voices for free using RVC (Retrieval-based Voice Conversion). This technology has taken the modding and gaming world by storm in 2025 because it runs locally—meaning no subscription fees and total privacy.

Prerequisites: Do You Have the Hardware?

Unlike cloud tools, RVC uses your computer’s power.

• GPU: NVIDIA Graphics Card with at least 8GB VRAM (RTX 3060 or better recommended).
• RAM: 16GB minimum.
• OS: Windows 10/11 (Linux is also supported).
• Alternative: If you have a weak PC, you can run RVC in the cloud using Google Colab (free tier available).

Step-by-Step Installation Guide

1. Download the Software:
   • Navigate to the official RVC-Project GitHub page or use the “AICoverGen” one-click installer package widely available on HuggingFace.
   • Download the .7z file (approx 5GB).
2. Unzip and Launch:
   • Extract the folder to a drive with at least 20GB of free space.
   • Run the file named go-web.bat. This opens a command prompt and eventually launches a user interface in your web browser.

How to Clone a Voice (Training Phase)

1. Prepare Your Dataset:
   • You need 10–30 minutes of clean audio of the target voice.
   • Crucial Step: RVC hates background noise and music. You must have clean, dry vocals. The best free tool for this is Ultimate Vocal Remover 5 (UVR5). Download it and use the “MDX-Net” model to separate vocals from instrumentals with high quality before feeding the audio to RVC.
2. Process Data:
   • In the RVC “Train” tab, name your model (e.g., “MyVoice_V1”).
   • Point the tool to your folder of audio clips.
   • Click “Process Data.” The AI will slice your audio into small chunks.
3. Start Training:
   • Set “Epochs” to 200 (for a balanced quality).
   • Click “Train Model.” Depending on your GPU, this will take 1–4 hours.

How to Use Your New Voice

Once trained, you get a .pth file.

1. Go to the “Model Inference” tab.
2. Click “Refresh” to see your new voice model.
3. Upload any audio file (e.g., you speaking into a mic) and click “Convert.” The AI will re-render your words in the cloned voice!

Troubleshooting Common Errors

“Deep/High Pitch”: You must adjust the “Pitch Semitone.” If converting Male-to-Female, set pitch to +12. If Female-to-Male, set to -12.

“Robotic / Metallic Sound”: This usually means you “Over-trained” the model (too many epochs). Try using an earlier save file (e.g., epoch 150 instead of 200).
