1. This is a client software for performing real-time voice conversion using various Voice Conversion (VC) AI. The supported AI for voice conversion are as follows.
The real-time voice changer of this application works on a server-client configuration. By running the MMVC server on a separate PC, you can run it while minimizing the impact on other resource-intensive processes such as gaming commentary.
You can run it on Google's machine learning platform, Colaboratory. If you have already used Colaboratory, you do not need to prepare anything as the training of MMVC model has been completed. However, the voice changer may have a large time lag depending on the network environment or the situation of Colaboratory.
- [Simple version](https://github.com/w-okada/voice-changer/blob/master/VoiceChangerDemo_Simple.ipynb): You can run it from Colab without any prior setup.
- [Normal version](https://github.com/w-okada/voice-changer/blob/master/VoiceChangerDemo.ipynb): You can load the model by cooperating with Google Drive.
- For Mac version, after unzipping the downloaded file, double-click the `startHttp.command` file corresponding to your VC. If a message indicating that the developer cannot be verified is displayed, please press the control key and click to run it again (or right-click to run it).
- Tsukuyomi-chan, Ami-taro, Kogane Mahiro, and Kogane Kaigetsu require the Content Vec model for their actions. Please download the ContentVec_legacy 500 model from [this repository](https://github.com/auspicious3000/contentvec) and place it in the same folder as startHttp.command or start_http.bat to execute it.
- To run DDSP-SVC, you need to download the hubert-soft and enhancer models. Download hubert-soft from [this link](https://github.com/bshall/hubert/releases/download/v0.1/hubert-soft-0d54a1f4.pt) and store it in the folder with the batch files. Download nsf_hifigan_20221211.zip from [this site](https://github.com/openvpi/vocoders/releases/tag/nsf-hifigan-v1) for enhancer. After unzipping, store the nsf_hifigan folder in the folder with the batch files.

## (2-3) Usage after setting up the environment such as Docker or Anaconda
Clone this repository and use it. Setting up WSL2 is essential for Windows. Additionally, setting up virtual environments such as Docker or Anaconda on WSL2 is also required. On Mac, setting up Python virtual environments such as Anaconda is necessary. Although preparation is required, this method works the fastest in many environments. **<fontcolor="red"> Even without a GPU, it may work well enough with a reasonably new CPU </font>(refer to the section on real-time performance below)**.
