In plain English

VCClient (Voice Changer Client) is a real-time AI voice changer application. It takes audio from your microphone and transforms it into a different voice on the fly, with low enough latency to use during live calls, streams, or gaming sessions. The tool supports several AI voice conversion models, most notably RVC (Retrieval-based Voice Conversion) and Beatrice v2. These are machine learning models trained to map one person's voice characteristics to another's. You load a model, speak into your microphone, and the software outputs the converted voice in real time. It can run entirely on your local computer, or it can offload the voice conversion processing to a separate machine over a network, which is useful when you want to run a voice changer at the same time as a resource-heavy application like a game. The software runs on Windows, Mac (M1), and Linux, with pre-built downloads available from Hugging Face for Windows and Mac users. On Windows it can leverage a CUDA-compatible graphics card (NVIDIA GPU) or run using ONNX, a cross-platform AI format, for faster processing. It also exposes a REST API, meaning other programs can control it programmatically. You would use VCClient if you want to change your voice during live streams, online gaming, Discord calls, or any situation where your microphone is active. The primary language in the repository is Japanese, and the application is written in Python.
