AI Voice Changer

Summary

AI Voice Changer is an open-source application for real-time voice conversion in streaming, gaming, content creation, and online communications. It uses SoftVC, ContentVec, or HuBERT feature extraction with retrieval-based RVC models and pitch-guided conversion. Audio tools include noise filtering, voice activity detection, pitch correction, formant shifting, equalization, compression, and reverb. The project describes virtual audio routing for OBS Studio, Discord, Zoom, Twitch, and other streaming or calling platforms, with routing options including VB-Audio Cable, BlackHole, and PipeWire or PulseAudio. A web dashboard at localhost:8000 provides model switching, audio adjustments, gain monitoring, and preset management. The FastAPI backend offers REST controls and real-time WebSocket streaming, and custom voice training covers dataset preparation through model training and feature indexing. The README gives a 35–48 ms delay target for specified hardware; CPU fallback is supported but can reach about 200 ms. It recommends a compatible NVIDIA GPU. The project also describes audio watermarking and requires consent and disclosure for voice cloning and AI synthesis.

Who it is for

It suits streamers, gamers, creators, and people who want voice conversion for calls, particularly those able to use the recommended NVIDIA GPU. Users can also train custom voices, but the guide calls for at least 10 minutes of clean continuous speech.
