Realtime AI Voice Changer Using RVC (Retrieval-based Voice Conversion w./ w-okada)

Introduction

In this article, we'll explore how to set up and use a real-time AI voice changer using the RVC (Retrieval-based Voice Conversion) models, specifically from the w-okada GitHub repository. This guide is designed to help you install, configure, and experiment with AI voice changing technology effectively.

Installation Steps

1. GitHub Repository
   Navigate to the w-okada GitHub repository where the voice changer is hosted. Scroll down to the English section of the documentation for clarity. Since this guide focuses on Windows installation, let's proceed with that.

2. Download the Necessary File
   Click on the appropriate link to download the file. You will be redirected to a Google Drive folder containing the installation files. Download the file, keeping in mind that it is unofficial software, so proceed at your own risk.

3. Extracting the Files
   Once the download completes, locate the downloaded file. Right-click on it and select "Extract All" to unpack the files. Once extracted, you can move the folder for easier access, then delete the original compressed file.

4. Running the Application
   Open the extracted folder and look for start_HTTP.bat. Running this script will initiate the program. Be aware that Windows Defender may prompt you regarding the executable's safety; choose to run it anyway.

5. Downloading Models
   Upon running the application, it will begin downloading necessary files from Hugging Face to function. This action may take time, so be patient.

6. Firewall Permission
   If prompted by Windows Defender Firewall asking to allow the application, grant it permission to run.

7. Selecting and Configuring the Voice
   Once the application is up, you will see options for different voice models. Select the desired voice (e.g., Tsukiyomi-chan) and configure the settings, such as frequency and chunk size. Adjust your input microphone settings accordingly.

8. Adjusting Additional Settings
   For optimal performance, you can tweak the advanced settings, including "Crossfade" and "Tran K." Be mindful of how these adjustments impact the audio quality.

9. Using Custom Models
   To add your own models, click on the edit button and select your .pth model file. The application should recognize and allow you to use this custom voice. You can also add associated images for added personalization.

10. Testing Voice Conversion
    After setting everything up, click "Start" to begin the voice conversion. Adjust output volume and settings as needed to achieve the desired effect.
